Narrative Report
On August 31, 1998 at 10:35 PM, New York - Covington experienced a crash involving Boeing 727-200, operated by DHL Worldwide Express - DHL Airways, with the event recorded near New York-JFK New York.
The flight was categorized as cargo and the reported phase was landing (descent or approach) at a airport (less than 10 km from airport) crash site.
5 people were known to be on board, 0 fatalities were recorded, 5 survivors were identified or estimated. This corresponds to an estimated fatality rate of 0.0%.
Crew on board: 5, crew fatalities: 0, passengers on board: 0, passenger fatalities: 0, other fatalities: 0.
The listed crash cause is technical failure. Shortly after takeoff, the No. 2 engine failed and shutdown procedures for the No. 2 engine were accomplished. The flight crew declared an emergency and requested to return to the airport. On approach, an engine out go-around was required as ATC had instructed the flight crew of a B-747 to "position and hold" on the end of the runway. The first officer was the pilot flying. Following an uneventful touchdown, as the airplane slowed to about 80 knots, the captain took control of the airplane. Shortly thereafter, the right main landing gear (MLG) collapsed and the airplane slid to a stop on the runway. Examination of the No. 2 engine revealed that 80 percent of the main fuel pump main drive shaft was worn to the spline root. The examination also revealed that the grease used to lubricate the main drive shaft output splines was not the authorized grease specified per OHM 73-11-1 or MIL-G-81322. Additionally, the magnetic seal compression O-ring that rides on the drive gear journal outer diameter was hardened and exhibited inner diameter axial cracks. The component manufacturer indicated that the failure of the magnetic seal was the first such reported incident in 30 years; however, it agreed to review operational data from airlines to reevaluate the mean time between overhaul intervals for the seal and to recommend an inspection interval, as necessary. Examination of the right MLG revealed a fracture failure of the trunnion bearing support fitting that was caused by fatigue cracking and stress corrosion cracking.
Aircraft reference details include registration N722DH, MSN 19861, year of manufacture 1969.
