Descripción:The captain of a Saudi Arabian Airlines Boeing 737-200 airplane aborted a takeoff from Doha Airport, Qatar, following a catastrophic and uncontained failure of the no. 2 engine. A fragment from the engine penetrated a wing fuel tank and the no.2 engine caught fire. The airplane was stopped on the end of the runway, and the 98 passengers and 6 crewmembers evacuated the airplane while the airport fire department extinguished the fire. There were no injuries to the occupants as a result of the engine failure and fire. Investigation of the accident disclosed that the 2nd stage low-pressure turbine (LPT) disk in the Pratt & Whitney JT8D-15 engine ruptured, and that a large segment of the disk exited the engine near the 1:30 o'clock position (aft looking forward). The released segment passed through the engine and caused substantial damage to the low-pressure nozzle case, the hush package and the fan bypass duct outer case. Considerable damage was inflicted on the no.2 engine nacelle by engine fragments and the ensuing fire.

Issued: 22-JUL-1985 | To: FAA | A-85-53 |
IDENTIFY THE PRATT & WHITNEY JT8D-15, -17, AND -17R SERIES ENGINES IN SERVICE THAT HAVE HAD REPAIRS MADE TO THE ROTATING OUTER AIR SEAL GROOVE IN THE 2ND STAGE LOW-PRESSURE TURBINE (LPT) DISK AND WHICH WERE NOT REASSEMBLED TO THE TOLERANCE IN SB-5510, AND REQUIRE EARLY DISASSEMBLY OF THE 2ND STAGE LPT MODULE FOR INSPECTION, REPAIR, AND REASSEMBLY IN ACCORDANCE WITH SB-5510, OR SOME OTHER APPROVED PROCEDURE. (Closed - Acceptable Action) |
Issued: 22-JUL-1985 | To: FAA | A-85-54 |
BECAUSE OF THE LIMITED OPERATIONAL EXPERIENCE WITH ENGINES MODIFIED IN ACCORDANCE WITH SB-5510, CONDUCT A DIRECTED SAFETY INVESTIGATION OF THE PRATT & WHITNEY JT8D-15, -17, AND -17R SERIES ENGINES AS LPT MODULES ARE DISASSEMBLED TO VERIFY THE EFFECTIVENESS OF THE TIGHTER FIT BETWEEN THE 2ND STAGE LPT DISK AND THE ROTATING OUTER AIR SEAL IN PREVENTING FATIGUE CRACKING OF THE DISK AT THE AIR SEAL GROOVE. (Closed - Acceptable Action) |
Issued: 22-JUL-1985 | To: FAA | A-85-55 |
CONDUCT A DIRECTED SAFETY INVESTIGATION OF THE PRATT & WHITNEY JT8D-15, -17, AND -17R SERIES ENGINES TO ESTABLISH AN APPROPRIATE INSPECTION PROGRAM FOR THE ENGINES THAT HAVE NOT HAD REPAIRS TO THE ROTATING OUTER AIR SEAL GROOVE IN THE 2ND STAGE LPT DISK TO ASSURE THE CONTINUED INTEGRITY OF THE DISKS. (Closed - Acceptable Action) |
Issued: 22-JUL-1985 | To: FAA | A-85-56 |
NOTIFY APPROPRIATE FOREIGN CIVIL AVIATION AUTHORITIES AND FOREIGN OPERATORS OF AIRPLANES EQUIPPED WITH PRATT & WHITNEY JT8D-15, -17, AND -17R SERIES ENGINES OF THE FAILURES ASSOCIATED WITH THE ROTATING OUTER AIR SEAL GROOVE ON THE 2ND STAGE LPT DISK IN THESE ENGINES AND OF THE ACTIONS WHICH SHOULD BE TAKEN TO MINIMIZE OR ELIMINATE THE FAILURES.
