Airworthiness Directives; Safran Helicopter Engines, S.A. (Type Certificate Previously Held by Turbomeca, S.A.) Turboshaft Engines
Document Number: 2021-05047
Type: Proposed Rule
Date: 2021-03-12
Agency: Federal Aviation Administration, Department of Transportation
The FAA proposes to supersede Airworthiness Directive (AD) 2014-04-06, which applies to all Safran Helicopter Engines, S.A. (Safran Helicopter Engines) Arrius 2B1, 2B1A, 2B2, and 2K1 model turboshaft engines. AD 2014-04-06 requires initial and repetitive inspections of the hydro-mechanical metering unit (HMU) high pressure pump drive gear shaft splines, cleaning and inspections of the sleeve assembly splines, and replacement of the sleeve assembly on the affected high pressure pump drive gear shaft or replacement of the HMU if the HMU fails inspection. Since the FAA issued AD 2014-04-06, the manufacturer has published new service information that revises the inspections for certain HMUs and reduces compliance times for initial inspections. This proposed AD would require revised inspections and continue to require cleaning of the sleeve assembly splines, and replacement of the sleeve assembly on the affected high pressure pump drive gear shaft or replacement of the HMU if the HMU fails an inspection. The FAA is proposing this AD to address the unsafe condition on these products.

Airworthiness Directives; Bell Textron Canada Limited Helicopters
Document Number: 2021-05093
Type: Proposed Rule
Date: 2021-03-11
Agency: Federal Aviation Administration, Department of Transportation
The FAA proposes to supersede Airworthiness Directive (AD) 2013-20-13 for certain Bell Helicopter Textron Canada Limited (now Bell Textron Canada Limited) (Bell) Model 206B and 206L helicopters. AD 2013-20-13 requires installing a placard beneath the engine power dual tachometer and revising the Operating Limitations section of the existing Rotorcraft Flight Manual (RFM) for your helicopter. Since the FAA issued AD 2013-20-13, the engine manufacturer expanded the RPM (N2) steady-state operation avoidance range limits. This proposed AD would retain certain requirements of AD 2013-20-13, require revising certain sections of the existing RFM for your helicopter, and require either replacing or installing a placard. The actions of this proposed AD are intended to address an unsafe condition on these products.
Airworthiness Directives; Airbus Helicopters
Document Number: 2021-05091
Type: Rule
Date: 2021-03-11
Agency: Federal Aviation Administration, Department of Transportation
The FAA is superseding Airworthiness Directive (AD) 2018-19- 01, which applied to all Airbus Helicopters Model AS-365N2, AS 365 N3, EC 155B, EC155B1, SA-365N1, and SA-366G1 helicopters. AD 2018-19-01 required repetitive inspections of the aft fuselage outer skin. This AD continues to require repetitive inspections and adds Model SA-365N helicopters, as specified in a European Union Aviation Safety Agency (EASA) AD, which is incorporated by reference. This AD was prompted by aft fuselage (baggage compartment area) outer skin disbonding and a determination that Model SA-365N helicopters are also affected by the unsafe condition identified in AD 2018-19-01. The FAA is issuing this AD to address the unsafe condition on these products.

Airworthiness Directives; Airbus Helicopters Deutschland GmbH
Document Number: 2021-05086
Type: Proposed Rule
Date: 2021-03-11
Agency: Federal Aviation Administration, Department of Transportation
The FAA proposes to adopt a new airworthiness directive (AD) for all Airbus Helicopters Deutschland GmbH Model MBB-BK 117 C-2 and Model MBB-BK 117 D-2 helicopters. This proposed AD was prompted by a determination that a life limit for the adapter forward (FWD) of the outboard load system, repetitive inspections of other components of that system, and for certain helicopters, a modification of the outboard load system, are necessary to address the unsafe condition. This proposed AD would require a modification of the outboard load system for certain helicopters, repetitive inspections of the outboard load system and its components for any defect (including cracking, damage, corrosion, and incorrect installation) and applicable corrective actions, and implementation of a new life limit for the FWD adapter, as specified in a European Aviation Safety Agency (EASA) AD, which is proposed for incorporation by reference (IBR).
