NTSB Safety Recommendation — Aviation
Recommendation text
THE NTSB RECOMMENDS THAT THE FEDERAL AVIATION ADMINISTRATION: CONDUCT A DIRECTED SAFETY INVESTIGATION OF THE BELL 206L HELICOPTER FUEL SYSTEM TO: (1) DETERMINE PROBLEMS THAT ALLOW INTERTANK TRANSFER OF FUEL UNDER STATIC CONDITIONS WHEN A LOW FUEL STATE EXISTS; (2) EVALUATE THE MINIMUM FUEL REQUIREMENTS FOR TAKEOFF, TAKING INTO CONSIDERATION THE POSSIBILITY OF AERATED FUEL BEING SUPPLIED TO THE ENGINE; AND (3) DETERMINE WHETHER A CONTINUOUS IGNITION SYSTEM WITH AN AUTOMATIC RELIGHT CAPABILITY SHOULD BE REQUIRED. FOLLOWING COMPLETION OF THE DIRECTED SAFETY INVESTIGATION, TAKE APPROPRIATE CORRECTIVE ACTION TO PRECLUDE ENGINE FLAMEOUT.
In plain language (FlightFinder summary)
The FAA is asked to conduct a directed safety investigation of the Bell 206L helicopter fuel system to identify problems allowing intertank fuel transfer under static low-fuel conditions, evaluate minimum takeoff fuel requirements considering the risk of aerated fuel, and determine if a continuous ignition system with automatic relight is needed. Following the investigation, appropriate corrective action should be taken to prevent engine flameout.
This plain-language summary is written by FlightFinder to explain the recommendation above. It is not the official wording — the verbatim NTSB text is quoted above.
