The pilot reported that, upon reaching the decision altitude on a GPS instrument approach, he saw the runway end identifier lights and continued the approach. Shortly after, the lights disappeared and then reappeared. He continued the approach and landing thinking the airplane was lined up with the runway by using the runway edge lights for reference. Upon touching down about 225 ft left of the runway, the airplane dug into snow and flipped over, which resulted in substantial damage to the wings and tail. The pilot reported that there were no preaccident mechanical malfunctions or failures with the airplane that would have precluded normal operation.

On October 28, 2016, about 1751 eastern daylight time, FedEx Express (FedEx) flight 910, a McDonnell Douglas MD-10-10F, N370FE, experienced a left main landing gear (MLG) collapse after landing on runway 10L at Fort Lauderdale–Hollywood International Airport (KFLL), Fort Lauderdale, Florida, and the left wing subsequently caught fire. The airplane came to rest off the left side of the runway. The two flight crew members evacuated the airplane. The captain reported a minor cut and abrasions from the evacuation, and the first officer was not injured. The airplane sustained substantial damage. The cargo flight was operating on an instrument flight plan under the provisions of Title 14 Code of Federal Regulation (CFR) Part 121 and originated at Memphis International Airport (KMEM), Memphis, Tennessee. The first officer was the pilot flying, and the captain was the pilot monitoring. Both flight crew members stated in post accident interviews that the departure from MEM and the en route portion of the flight were normal. About 1745, air traffic control (ATC) cleared the flight for final approach to the instrument landing system (ILS) approach to runway 10L at KFLL. Recorder data indicate that the first officer set the flaps at 35º about 1746 when the airplane was 3,000 ft above ground level (agl). The first officer disconnected the autopilot about 1749 when the airplane was 1,000 ft agl. Both flight crew members reported that the approach was stable at 500 ft agl. At 200 ft agl, the first officer began making airspeed corrections to compensate for the crosswind. About 1750, the first officer disconnected the autothrottles, as briefed, when the airplane was at 100 ft agl. At 50 ft agl, the first officer initiated the flare. The left MLG touched down about 1750:31 in the touchdown zone and left of the runway centerline. The first officer deployed the spoilers at 1750:34, and the nose gear touched down 3 seconds later. The thrust reversers were deployed at 1750:40. According to cockpit voice recorder (CVR) data, the captain instructed the first officer to begin braking about 1750:39 (the airplane was not equipped with autobrakes). FDR data indicate an increase in brake pedal position angle and increase in longitudinal deceleration (indicating braking) about 1750:41. In post accident interviews, the flight crew members reported hearing a "bang" as the first officer applied the brakes, and the airplane yawed to the left. About this time, the CVR recorded the sound of multiple thuds, consistent with the sound of a gear collapse. About 1750:48, the captain stated, "I have the airplane," and the first officer replied, "you got the airplane." The captain applied full right rudder without effect while the first officer continued braking. About 1750:53, the captain instructed the first officer to call and inform the tower about the emergency. An airport video of the landing showed that the No. 1 engine was initially supporting the airplane after the left MLG collapse when a fire began near the left-wing tip. The airplane eventually stopped off the left side of runway 10L, about 30º to 40º off the runway heading. About 1751, the flight crew began executing the evacuation checklist. The pilots reported that, as they were about to evacuate, they heard an explosion. The airport video showed a fireball erupted at the No. 1 engine. The captain attempted to discharge a fire bottle in the No. 1 engine, but it didn't discharge. They evacuated the airplane through the right cockpit window.

The pilot departed San Juan-Luis Muñoz Marín Airport at 1049LT on a cargo flight to Basseterre-Robert L. Bradshaw International Airport, Saint Kitts & Nevis. The flight was performed by Mountain Air Cargo on behalf of FedEx. The pilot continued the flight at FL110 until 1139LT, reduced his altitude down to FL100 and maintained this level until 1153LT. At this moment, the aircraft was descending between 600 and 800 feet per minute and the pilot decided to divert to the Juancho E. Yrausquin Airport located on Saba Island, Dutch Antilles. While approaching to island from the south, the pilot realized he would not make it, so he attempted to ditch the aircraft some 900 metres off shore. The pilot evacuated the cabin and was quickly rescued while the aircraft sank by a depth of about 1,500 feet. According to the pilot, he decided to divert to the nearest airport due to a loss of engine power.

On behalf of Morningstar Air Express, the pilot departed Sault Sainte Marie Airport, south Ontario, in the morning, for a local training flight. For unknown reasons, the pilot did not maintain any radio contact with his base or ATC and continued to the north for about 1,200 km when the aircraft crashed in unknown circumstances in the Hudson Bay, some 500 km east of Churchill, Manitoba. The aircraft was destroyed and the pilot was killed.

The aircraft was substantially damaged when it collided with a hedgerow during a forced landing following a loss of engine power near Wichita, Kansas. The loss of engine power occurred about 4-1/2 minutes after departing Wichita Mid-Continent Airport (ICT), Wichita, Kansas. The commercial pilot, who was the sole occupant, was fatally injured. The airplane was registered to the Federal Express Corporation and operated by Baron Aviation Services Incorporated, under the provisions of 14 Code of Federal Regulations Part 135 while on an instrument flight plan. Day visual meteorological conditions prevailed for the cargo flight that had the intended destination of Garden City Regional Airport (GCK), Garden City, Kansas. According to air traffic control transmissions, at 0734:35 (hhmm:ss), the pilot requested an instrument flight rules clearance from ICT to GCK. Radar track data indicated that the airplane departed runway 19R approximately 0737:45. At 0738:18, the tower controller told the pilot to change to the departure control frequency. The departure controller then cleared the flight to proceed direct to GCK and to climb to 8,000 ft mean sea level (msl). The airplane continued to climb on a westerly heading until 0742:02, at which time the airplane began a left 180-degree turn back toward the departure airport. According to radar data, the airplane had reached 4,700 ft msl when it began the left turn. At 0742:13, the pilot transmitted that his airplane had experienced a loss of engine power and that he was attempting to return to the departure airport. At 0742:31, the pilot asked if there were any nearby airports because he was unable to reach ICT. The departure controller provided vectors toward an airstrip that was approximately 2.5 miles southeast of the airplane's position. At 0743:46, the pilot advised that he could not see the airstrip because the airplane's windshield was contaminated with oil. At 0744:57, the pilot's final transmission was that he was landing in a grass field. The airplane was located about 2.2 miles south of ICT at 1,600 feet msl, about 300 feet above ground level (agl) at the time of the last transmission. The radar data continued northeast another 1/2 mile before radar contact was lost at 0745:15. A witness to the accident reported that he was outside his residence when he observed the accident airplane overfly his position. He recalled that the airplane's propeller was not rotating and that he did not hear the sound of the engine operating. He stated that the airplane landed in a nearby agricultural field on a northeast heading. He reported that during the landing rollout the airplane impacted a hedgerow located at the northern edge of the field. The witness indicated that the pilot was unresponsive when he arrived at the accident site and that there was a small grass fire located 8 to 10 feet in front of the main wreckage.

Aircraft bounced repeatedly during landing on Runway 34L at Narita International Airport. During the course of bouncing, its left wing was broken and separated from the fuselage attaching point and the airplane caught fire. The airplane rolled over to the left being engulfed in flames, swerved off the runway to the left and came to rest inverted in a grass area. The Pilot in Command (PIC) and the First Officer (FO) were on board the airplane, and both of them suffered fatal injuries. The airplane was destroyed and the post-crash fire consumed most parts.

ATR42-300

Aircraft was on an instrument approach when it crashed short of the runway at Lubbock Preston Smith International Airport, Lubbock, Texas. The captain sustained serious injuries, and the first officer sustained minor injuries. The airplane was substantially damaged. The airplane was registered to FedEx Corporation and operated by Empire Airlines, Inc., as a 14 Code of Federal Regulations Part 121 supplemental cargo flight. The flight departed from Fort Worth Alliance Airport, Fort Worth, Texas, about 0313. Instrument meteorological conditions prevailed, and an instrument flight rules flight plan was filed.

The airplane was on a visual approach to an airport when the engine stopped producing power. The pilot subsequently landed the airplane in a field, but struck trees at the edge of the field during the forced landing. Examination of the engine, engine fuel controls, and Power Analyzer and Recorder (PAR), provided evidence that the engine shut down during the flight. Further examination of engine and fuel system components from the accident airplane failed to reveal a definitive reason for the uncommanded engine shut-down.

The approach and landing were stabilized and within specified limits. Recorded data indicates that the loads experienced by the landing gear at touchdown were within the certification limits for an intact landing gear without any pre-existing cracks or flaws. The weather and runway conditions did not affect the landing. The application of braking by the accident crew, and the overall effect of the carbon brake modification did not initiate or contribute to the landing gear fracture. Post-accident modifications to the MD-10 carbon brake system were implemented due to investigative findings for the purposes of braking effectiveness and reliability. Post accident emergency response by the flight crew and ARFF was timely and correct. The left main landing gear (LMLG) outer cylinder on the accident airplane had been operated about 8 ½ years since its last overhaul where stray nickel plating likely was introduced in the air filler valve hole. Nickel plating is a permissible procedure for maintaining the tolerances of the inner diameter of the outer gear cylinder, however the plating is not allowed in the air filler valve bore hole. Literature and test research revealed that a nickel plating thickness of 0.008" results in a stress factor increase of 35%. At some point in the life of the LMLG, there was a load event that compressively yielded the material in the vicinity of the air filler valve hole causing a residual tension stress. During normal operations the stress levels in the air filler valve hole were likely within the design envelope, but the addition of the residual stress and the stress intensity factor due to the nickel increased these to a level high enough to initiate and grow a fatigue crack on each side of the air filler valve hole. The stresses at the air filler valve hole were examined via development of a Finite Element Model (FEM) which was validated with data gathered from an instrumented in-service FedEx MD-10 airplane. The in-service data and FEM showed that for all of the conditions, the stress in the air filler valve hole was much higher than anticipated in the design of the outer cylinder. Fatigue analysis of the in service findings and using the nickel plating factor resulted in a significantly reduced fatigue life of the gear cylinder compared with the certification limits. During the accident landing the spring back loads on the LMLG were sufficient to produce a stress level in the air filler valve hole that exceeded the residual strength of the material with the fatigue cracks present.

The pilot stated that during takeoff, "after becoming airborne, the airplane quit accelerating and a positive climb rate was not established." He pushed the power lever all the way forward, but did not feel a response from the airplane. Witnesses reported that the airplane became airborne, but failed to gain altitude and struck an antenna array and a fence off the departure end of the runway. The airplane continued across a slough, struck an embankment and came to rest about 900 feet from the departure end of the runway on a golf course located adjacent to the airport. Examination of the airplane revealed no pre-mishap airframe anomalies. Examination of the engine revealed that the compressor and power turbines displayed moderate circular rubbing damage to the blades suggesting engine operation at impact, likely in the low to mid power range. Examination of the airframe and engine revealed no anomalies that would have prevented the engine from producing power prior to impact. The reason for the partial loss of engine power was not determined.
