Airworthiness Directives; Leonardo S.p.a. Helicopters
The FAA is adopting a new airworthiness directive (AD) for certain Leonardo S.p.a. Model AW119 MKII helicopters. This AD was prompted by reports of detected smoke and burning smell during flight, caused by chafing of electrical wiring. This AD requires an inspection of the instrument panel electrical wiring, corrective actions if necessary, a modification of the wiring installation, and, for certain helicopters, an additional modification of the wiring installation, as specified in a European Union Aviation Safety Agency (EASA) AD, which is incorporated by reference. The FAA is issuing this AD to address the unsafe condition on these products.
Supplemental Type Certificates ST03718AT, SA03654AT; Original Product Type Certificate Numbers A32NM, T00006LA, A4SW
This notice announces that Avenger Aerospace Solutions, Inc. has surrendered its supplement type certificates, ST03718AT and SA03654AT to the FAA. In accordance with policy, the FAA announces surrender of aircraft certificates in the Federal Register.
Airworthiness Directives; Yaborã Indústria Aeronáutica S.A. (Type Certificate Previously Held by Embraer S.A.) Airplanes
The FAA is superseding Airworthiness Directive (AD) 2020-08- 11, which applied to all Yabor[atilde] Ind[uacute]stria Aeron[aacute]utica Model ERJ 190- 300 and ERJ 190-400 airplanes. AD 2020-08-11 required revising the existing airplane flight manual (AFM) procedures associated with messages of smoke in the electronic bays presented on the respective engine indication and crew alerting system (EICAS). This AD continues to require revising the existing AFM procedures, and adds requirements for a terminating modification of the electrical wiring of the mid- electronic bay and backup smoke detectors; as specified in an Ag[ecirc]ncia Nacional de Avia[ccedil][atilde]o Civil (ANAC) AD, which is incorporated by reference. This AD was prompted by a failure propagation test, which revealed that under certain conditions, the smoke detection system of the electrical bays erroneously indicated the presence of smoke via the respective EICAS messages. The FAA is issuing this AD to address the unsafe condition on these products.
Airworthiness Directives; Bombardier, Inc., Airplanes
The FAA proposes to adopt a new airworthiness directive (AD) for certain Bombardier, Inc., Model BD-700-1A10 and BD-700-1A11 airplanes. This proposed AD was prompted by reports that the sliding bushings in the forward engine mount system were missing. This proposed AD would require an inspection (gap check) of the front and aft engine mounts to verify the proper installation of the sliding bushings, and repair if necessary. The FAA is proposing this AD to address the unsafe condition on these products.
Establishment of Class E Airspace; Missoula, MT
This action establishes Class E domestic en route airspace extending upward from 1,200 feet above the surface at Missoula, MT. This airspace facilitates vectoring of instrument flight rules (IFR) aircraft and properly contains IFR aircraft operating on direct routes under the control of Salt Lake City Air Route Traffic Control Center (ARTCC) and Seattle ARTCC.
Establishment of Class E Airspace; Mountain Home, ID
This action establishes Class E domestic en route airspace extending upward from 1,200 feet above the surface at Mountain Home, ID. This airspace facilitates vectoring of instrument flight rules (IFR) aircraft and properly contains IFR aircraft operating on direct routes under the control of Salt Lake City Air Route Traffic Control Center (ARTCC).
Amendment of Class E Airspace; Missoula, MT; Correction
The Federal Aviation Administration (FAA) is correcting a final rule that appeared in the Federal Register on June 16, 2021. The rule modified the Class E airspace extending upward from 1,200 feet above the surface at Missoula International Airport, Missoula, MT. The Final Rule inadvertently used the word ``about'' instead of ``above'' when describing the airspace area. This action corrects the legal description for the Class E airspace extending upward from 1,200 feet above the surface.
Airworthiness Directives; Safran Helicopter Engines, S.A. (Type Certificate Previously Held by Turbomeca, S.A.) Turboshaft Engines
The FAA is adopting a new airworthiness directive (AD) for certain Safran Helicopter Engines, S.A. (Safran Helicopter Engines) Arriel 2B, 2B1, 2C, 2C1, 2C2, 2S1 and 2S2 model turboshaft engines. This AD was prompted by reports of non-conforming fuel filter pre- blockage pressure switches. This AD requires repetitive visual inspections of the fuel filter by-pass indicator pop-up, a one-time operational test of the fuel filter pre-blockage pressure switch and, depending on the findings, replacement of the fuel filter pre-blockage pressure switch with a part eligible for installation. The FAA is issuing this AD to address the unsafe condition on these products.
Airworthiness Directives; Hélicoptères Guimbal Helicopters
The FAA proposes to adopt a new airworthiness directive (AD) for H[eacute]licopt[egrave]res Guimbal Model Cabri G2 helicopters with any metal bushing installed on the main rotor (M/R) swashplate guide bellcrank. This proposed AD was prompted by a report of cracks discovered on the M/R scissor link during scheduled maintenance on several helicopters. This proposed AD would require removing all metal bushings from service, visually inspecting the lug bore area and depending on the inspection results, removing certain parts from service and installing certain part-numbered plastic bushings. This proposed AD would also prohibit installing any metal bushing on any helicopter. The FAA is proposing this AD to address the unsafe condition on these products.
