AWB 85-022 Issue 1 Pratt & Whitney R-1340 Wasp engines cylinder head inspection practices. This AWB advises operators and maintenance providers of the potential for cylinder head cracking on these engines. It recommends certain actions at every visual inspection required by AD DCA/P&W/110 (FAA AD 99-11-02 refers). A fluorescent penetrant inspection (FPI) is also recommended of the entire cylinder for evidence of cracking at every cylinder overhaul. 18 Oct 2017
AWB 24-012 Issue 1

This AWB provides information for accomplishing capacity tests to determine serviceability of lead acid batteries. Failures of batteries can result in costly AOG situations and catastrophic inflight emergencies.FAA AC 23.1309-1E states failure of electrical power is a catastrophic failure condition if primary flight instruments require electrical power. Batteries that have been discharged to the point where their cranking power has been diminished must NOT be jumped with another power source. The discharged battery may not be airworthy because it does not have the necessary capacity required to operate the aircraft avionics and electrical system in the event of generator failure.

The purpose of this Civil Aviation Safety Alert (CASA) is to ensure that affected operators are aware that use of tail rotor pitch change chain assembly P/N 205-001-721-001 for Bell 204B helicopters is no longer supported by Bell Helicopter.

Affected tail rotor pitch change chain assembly may also be installed on other Bell helicopter models.

CASA 2017-02 Issue 01 The purpose of this Civil Aviation Safety Alert (CASA) is to raise awareness of several occurrences where critical hardware was found missing from tail rotor drive shaft flexible couplings on Bell 206A, 206B, 206B-3, 206L-1, 206 L-3 AND 206L-4 helicopters and to recommend strict adherence to Bell Helicopter maintenance practices that reduce the likelihood of this type of failure 29 Mar 2017

CASA 2016-11

The purpose of this CASA is to emphasize the importance to thoroughly examine the engine mount legs on Bell model 206L-series helicopters and replace deteriorated parts.
Operators have submitted Service Difficulty Reports noting that engine mount legs have been found corroded and/or cracked. On the 206L-series helicopters, there are six legs that hold the engine in place. In some cases the damage was not obvious because a wiring or tubing support clamp was installed on the leg, hiding the damage. In some cases, there have been reports of significant corrosion-related damage on the inside of the part where it would not be visible during inspection.
Bell Helicopter Textron Canada issued Operation Safety Notice 206L-15-51 to owners and operators of model 206L-1 and 206L-3 helicopters to highlight the criticality of inspection of the engine mount legs. That document also informs operators that Bell Helicopter has introduced engine mount legs made of CRES (stainless steel), noting that these parts have improved resistance to corrosion. It concludes by clarifying what components of the legs can be replaced and noting some important considerations that apply during inspection and reassembly.
Transport Canada and another civil aviation authority have obtained information that the CRES parts have also been reported cracked and corroded, and are not immune to degradation.
