Control Cable Terminal - Inspection and Replacement

Note: This AWB is applicable to all aircraft flight control cable terminal fittings made from stainless steel specification SAE-AISI 303 Se or SAE-AISI 304, installed on aircraft which are not maintained in accordance with a maintenance program which was developed using MSG-3 methodology.

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.

FAA Notice of availability of list of helicopters that are fully compliant with the latest crash resistant fuel system (CRFS) safety standards, with the following CAANZ explanatory note.

NOTE: The FAA list is based on the original airworthiness certification basis listed under the helicopter type certificate. Some manufacturers or aftermarket companies have produced upgrades which can be retrofitted to a helicopter to modify or add a fuel tank that meets CRFS safety standards.

Examples of this include:

1. Robinson Service Bulletin SB-78B for the Robinson R44. (This has been mandated in New Zealand under Airworthiness Directive DCA/R44/30.)
2. FAA-approved STC SR03931NY, which embodies a crash-resistant fuel system to the Airbus Helicopters Model AS350B3 fitted with an Arriel 2D engine.

The purpose of this Civil Aviation Safety Alert (CASA) is to raise awareness of reported defects on the Airwolf Aerospace, LLC (Airwolf) Tension[1]Torsion (TT) Strap assemblies installed on all Bell 204, 205, 206, 210 and 212 model helicopters. This CASA recommends inspecting the Airwolf TT strap assemblies at the earliest opportunity.

The purpose of this Civil Aviation Safety Alert (CASA) is to:

1. raise awareness about the potential risk associated with the transportation in the flight deck of portable electronic devices (PEDs) powered by lithium batteries that are not part of the aeroplane type design, lithium battery power banks or spare lithium batteries;
2. provide recommendations to mitigate that risk; and
3. provide guidance on how to implement those recommendations.

Pratt & Whitney PT6B-37A engines fitted with a fuel control unit overhauled after December 2016. P&W Service Information Letter (SIL) No PT6B-045 refers.

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.

The purpose of this Civil Aviation Safety Alert (CASA) is to raise awareness of the possibility of cracking and potential failures of control columns installed on Piper PA-28 series of aircraft.

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.

• The vulnerability of the main transmission freewheel lubrication system to contamination.
• To emphasize how critical it is to ensure a conforming filter is installed.
• To follow the manufacturer's recommended procedures for aircraft storage and reactivation
