Dual Engine Failure blamed for MD-80 crash
Interesting... given the lack of obvious causes ...
A preliminary report on the June 3 crash (ATW Daily News, June 5) released by the AIC does not reach a conclusion as to why the MD-83’s two Pratt & Whitney JT8D-219 engines each experienced “a total loss of power” during final approach. It noted an examination of maintenance records and fuel used by the flight showed the aircraft had enough fuel and it was not contaminated.
“The airplane was on the fourth flight segment of the day, consisting of two round-trips between Lagos [LOS] and Abuja,” the AIC report, completed with assistance from the US National Transportation Safety Board, stated. “The accident occurred during the return leg of the second trip. [Flight] 992 was on final approach for runway 18R at LOS when the crew reported the total loss of power.”
The cockpit voice recorder (CVR) has about 31 minutes of recordings from the MD-83’s pilots, and reveals that they were engaged in pre-landing tasks including deployment of the slats and extension of the flaps and landing gear.
As this was happening, according to the CVR transcript, the first officer asked, “Both engines coming up?” The captain replied, “Negative.” They then radioed an emergency distress call stating “dual engine failure” and “negative response from throttle."
The aircraft “crashed in a residential area about 5.8 mi. north of LOS,” the AIC report said. “The airplane wreckage was on approximately the extended centerline of runway 18R. During the impact sequence, the airplane struck an incomplete building, two trees and three buildings. The wreckage was confined, with the separated tail section and engines located at the beginning of the debris field. The airplane was mostly consumed by post-crash fire.”
According to Flight Safety Foundation’s Aviation Safety Network, wind at the time of the crash was just 7 knots, visibility was 10 km.-plus and there were “scatter[ed] clouds at 1,400 ft.”

From the report:
The cockpit voice recorder (CVR) retained about 31
minutes of the flight and starts about 1515 at which time
the captain and first officer were in a discussion of a nonnormal
condition regarding the correlation between the
engine throttle setting and an engine power indication3.
However, they did not voice concerns then that the
condition would affect the continuation of the flight. The
flight crew continued to monitor the condition and became
increasingly concerned as the flight transition through the
initial descent from cruise altitude at 1522 and the
subsequent approach phase.

The captain (55, ATPL, 18,116 hours total experience, 7,461 hours on type) had been employed with Dana Air since Mar 14th 2012, the first officer (34, CPL, 1,143 hours total, 808 hours on type) had been hired by Dana Air in January 2011.
Just WOW!!!!

Could the airplane have experienced the same issue as that 777 into Heathrow?
