Airworthiness Directive · Amendment 39-19391 · Engine air intake system
Airbus Helicopters
Superseded. A later AD replaced this one: AD 2019-16-16. Comply with the one in force.
This AD applies to Model AS350B, AS350B1, AS350B2, AS350B3, and AS350BA helicopters, certificated in any category, with a Pall Aerospace Inlet Barrier Filter element part number CE01301F2 or CE01301F2B installed.
We are adopting a new airworthiness directive (AD) for Airbus Helicopters Model AS350B, AS350B1, AS350B2, AS350B3, and AS350BA helicopters with a Pall Aerospace Corporation inlet barrier filter (IBF) element. This AD requires revising the Rotorcraft Flight Manual Supplement to prohibit operating a helicopter with an IBF element in wet weather and replacing the IBF element if wet. This AD is prompted by a forced landing after an engine flameout. The actions of this AD are intended to address an unsafe condition on these products.
You are responsible for performing each action required by this AD within the specified compliance time unless it has already been accomplished prior to that time.
Within 30 days, revise the rotorcraft flight manual supplement (RFMS) by inserting Appendix A of this AD into the limitations section of the RFMS.
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.
