Proposed Amendment of VOR Federal Airways V-26, V-193, and V-285, and Revocation of White Cloud, MI, Domestic Low Altitude Reporting Point in the Vicinity of White Cloud, MI
Document Number: 2021-24623

Airworthiness Directives; Pratt & Whitney Division Turbofan Engines
Document Number: 2021-24574
Type: Rule
Date: 2021-11-12
Agency: Federal Aviation Administration, Department of Transportation
The FAA is superseding Airworthiness Directive (AD) 2021-05-16 for certain Pratt & Whitney Division (PW) PW4164, PW4164-1D, PW4168, PW4168-1D, PW4168A, PW4168A-1D, and PW4170 model turbofan engines. AD 2021-05-16 required initial and repetitive replacements of the low- pressure turbine (LPT) 4th-stage air sealing ring segment assemblies with parts eligible for installation. AD 2021-05-16 also required initial and repetitive dimensional inspections of the LPT case for bulging and, depending on the results of the dimensional inspections, repair or replacement of the LPT case. This AD was prompted by notification to the FAA of an inadvertent omission in the LPT 4th-stage air sealing ring segment assembly part numbers. This AD requires initial and repetitive replacements of the LPT 4th-stage air sealing ring segment assemblies with parts eligible for installation. This AD also requires initial and repetitive dimensional inspections of the LPT case for bulging and, depending on the results of the dimensional inspections, repair or replacement of the LPT case. The FAA is issuing this AD to address the unsafe condition on these products.
Amendment of VOR Federal Airways V-31, V-36, V-84, V-252, and V-510 in the Vicinity of Buffalo, NY
Document Number: 2021-24559
Type: Rule
Date: 2021-11-12
Agency: Federal Aviation Administration, Department of Transportation
This action amends VHF Omnidirectional Range (VOR) Federal airways V-31, V-36, V-84, V-252, and V-510. This action is necessary due to the planned decommissioning of the VOR portion of the Buffalo, NY, VOR/Distance Measuring Equipment (VOR/DME) navigational aid, which provides navigational guidance for these airways. The Buffalo VOR is being decommissioned as part of the FAA's VOR Minimum Operational Network (MON) program. The VOR Federal airways V-2, V-14, V-33, and V-164 modifications proposed in the notice of proposed rulemaking have been accomplished by separate rules subsequently published. As a result, the V-2, V-14, V-33 and V-164 modifications are removed from this rule.
Airworthiness Directives; Airbus Helicopters
Document Number: 2021-24544
Type: Rule
Date: 2021-11-12
Agency: Federal Aviation Administration, Department of Transportation
The FAA is removing Airworthiness Directive (AD) 2021-05-02, which applied to all Airbus Helicopters Model AS350B, AS350BA, AS350B1, AS350B2, AS350B3, AS350C, and AS350D helicopters; Model AS355E, AS355F, AS355F1, AS355F2, AS355N, and AS355NP helicopters; and Model EC130B4 and EC130T2 helicopters. AD 2021-05-02 required determining whether the helicopter has been operated in a severe environment since the last inspection of the main rotor hub-to-mast attachment screws, an inspection of the main rotor hub-to-mast attachment screws if the helicopter has been operated in a severe environment, and replacement of the main rotor hub-to-mast attachment screws if necessary, as specified in a European Aviation Safety Agency (now European Union Aviation Safety Agency) (EASA) AD, which was incorporated by reference. Since the FAA issued AD 2021-05- 02, reported inspection results and further investigation have confirmed that the report of failed main rotor hub-to-mast attachment screws, which prompted AD 2021-05-02, was an isolated case which resulted from a maintenance mistake. Therefore, the FAA has determined that no unsafe condition is likely to exist or develop on the main rotor hub-to-mast attachment screws on other helicopters in the fleet. Accordingly, AD 2021-05-02 is removed.
Airworthiness Directives; Hélicoptères Guimbal Helicopters
Document Number: 2021-24541
Type: Rule
Date: 2021-11-12
Agency: Federal Aviation Administration, Department of Transportation
The FAA is adopting a new airworthiness directive (AD) for H[eacute]licopt[egrave]res Guimbal (HG) Model Cabri G2 helicopters with certain part-numbered aluminum cooling fans (cooling fan) installed. This AD was prompted by a report of an occurrence of an in-flight shutdown due to a crack and subsequent failure of the cooling fan. This AD requires removing certain part-numbered cooling fans from service, or modifying certain part-numbered cooling fans before exceeding a certain total hours time-in-service (TIS), and installing newly designed cooling fans. This AD also prohibits installing any affected cooling fan on any helicopter. The FAA is issuing this AD to address the unsafe condition on these products.
Airworthiness Directives; Pilatus Aircraft Ltd. Airplanes
Document Number: 2021-24540
Type: Proposed Rule
Date: 2021-11-12
Agency: Federal Aviation Administration, Department of Transportation
The FAA proposes to adopt a new airworthiness directive (AD) for certain Pilatus Aircraft Ltd. (Pilatus) Model PC-12/47E airplanes. This proposed AD results from mandatory continuing airworthiness information (MCAI) originated by an aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI identifies the unsafe condition as inward vent valves installed during production without chromate conversion coating on the bonding surface. This proposed AD would require modifying the inward vent valves and prohibiting installation of unmodified inward vent valves. The FAA is proposing this AD to address the unsafe condition on these products.
Airworthiness Directives; British Aerospace (Operations) Limited and British Aerospace Regional Aircraft Airplanes
Document Number: 2021-24539
Type: Proposed Rule
Date: 2021-11-12
Agency: Federal Aviation Administration, Department of Transportation
The FAA proposes to adopt a new airworthiness directive (AD) for certain British Aerospace (Operations) Limited and British Aerospace Regional Aircraft Model Jetstream Series 200, Jetstream Model 3101, and Jetstream Model 3201 airplanes. This proposed AD was prompted by mandatory continuing airworthiness information (MCAI) originated by an aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI identifies the unsafe condition as a bent control rod within the gust lock system, which may enable both power levers to be pushed into the flight range with the gust lock lever fully engaged. This proposed AD would require replacing the push rod assembly with a modified push rod assembly. The FAA is proposing this AD to address the unsafe condition on these products.
Airworthiness Directives; Leonardo S.p.a. Helicopters
Document Number: 2021-24538
Type: Proposed Rule
Date: 2021-11-12
Agency: Federal Aviation Administration, Department of Transportation
The FAA proposes to adopt a new airworthiness directive (AD) for all Leonardo S.p.a. Model AB139 and AW139 helicopters. This proposed AD was prompted by the identification of certain parts needing maintenance actions, including life limits and maintenance tasks. This proposed AD would require incorporating into maintenance records requirements (airworthiness limitations), as specified in a European Aviation Safety Agency (now European Union Aviation Safety Agency) (EASA) AD, which is proposed for incorporation by reference (IBR). The FAA is proposing this AD to address the unsafe condition on these products.
