Airworthiness Directive · Amendment 39-11033 · Rolls-Royce Limited Dart Series Turboprop Engines
Rolls-Royce Limited Dart Series Turboprop Engines
Rolls-Royce Limited (R-R) Dart 525 series, 526, 527, 528 series, 529 series, 530, 531, 532 series, 535 series, 542 series, and 552 series turboprop engines, installed on but not limited to Gulfstream Aerospace Corp. G-159, British Aerospace HS 748, Fokker Aircraft F27, Fairchild Hiller FH227, Mitsubishi Heavy Industries YS-11, General Dynamics (Convair) 640 and 600 series, and Vickers Armstrong (Aircraft Limited) Viscount aircraft.
This amendment adopts a new airworthiness directive (AD) that is applicable to Rolls-Royce Limited (R-R) Dart series turboprop engines. This action requires initial and repetitive fuel burner fuel flow calibration checks, and overhaul or replacement of fuel burners. This amendment is prompted by reports of an uncontained engine failure and fire due to HPT disk rupture caused by fuel burner failure. The actions specified in this AD are intended to prevent HPT disk rupture, which can result in an uncontained engine failure, engine fire, and damage to the aircraft.
The aircraft, engines and makers this AD names, by the model designations in its text. A model listed here may still be outside the AD's serial ranges.
