Amendment of Class D and Class E Airspace; Pensacola, FL, and Establishment of Class E Airspace; Milton, FL
This action corrects a final rule published in the Federal Register on August 29, 2018, amending Class D airspace and Class E airspace extending upward from 700 feet above the surface, and establishing Class E surface airspace at Choctaw Naval Outlying Field (NOLF), Milton, FL. Additional text was inadvertently omitted from the NOTAM information of Class D airspace and Class E surface airspace for Choctaw NOLF.
Airworthiness Directives; GEVEN S.p.A. Seat Assemblies, Type D1-02 and D1-03
We are adopting a new airworthiness directive (AD) for certain GEVEN S.p.A. (Geven) Type D1-02 and D1-03 seat assemblies. This AD was prompted by a report that seat belt attachment bolts were found detached or partially detached from the seat. This AD requires inspection, torque verification, and modification of certain model seats. We are issuing this AD to address the unsafe condition on these products.
Airworthiness Directives; General Electric Company Turbofan Engines
We are adopting a new airworthiness directive (AD) for all General Electric Company (GE) CF34-10A16, CF34-10E2A1, CF34-10E5, CF34- 10E5A1, CF34-10E6, CF34-10E6A1, CF34-10E7, and CF34-10E7-B turbofan engines with certain high-pressure turbine (HPT) front rotating air seals. This AD requires replacement of the affected HPT front rotating air seal. This AD was prompted by cracks found in the HPT front rotating air seal. We are issuing this AD to address the unsafe condition on these products.
Airworthiness Directives; Pratt & Whitney Division (PW) Turbofan Engines
We propose to adopt a new airworthiness directive (AD) for certain Pratt & Whitney Division (PW) PW4074, PW4074D, PW4077, PW4077D, PW4084D, PW4090, and PW4090-3 turbofan engines. This proposed AD was prompted by an in-flight failure of a 1st stage low-pressure compressor (LPC) blade. This proposed AD would require initial and repetitive thermal acoustic imaging (TAI) inspections for cracks in certain 1st stage LPC blades and removal of those blades that fail inspection. We are proposing this AD to address the unsafe condition on these products.
Airworthiness Directives; Pratt & Whitney Turbofan Engines
We propose to supersede Airworthiness Directive (AD) 2017-11- 06, which applies to all Pratt & Whitney (PW) PW2037, PW2037D, PW2037M, PW2040, PW2040D, PW2043, PW2143, PW2643, and F117-PW-100 turbofan engine models. AD 2017-11-06 requires initial and repetitive on-wing eddy current inspections (ECIs) of affected engines with certain diffuser and high-pressure turbine (HPT) cases installed. AD 2017-11-06 also requires a fluorescent-penetrant inspection (FPI) of the diffuser case rear flange and the HPT case front flange. Since we issued AD 2017-11-06, we learned of designated engineering representative (DER)- approved diffuser case M-flange replacement repairs. This proposed AD would require an on-wing ECI of all diffuser case M-flange replacement repairs. We are proposing this AD to address the unsafe condition on these products.
Airworthiness Directives; CFM International S.A. Turbofan Engines
We are adopting a new airworthiness directive (AD) for all CFM International S.A. (CFM) LEAP-1A23, -1A24, -1A24E1, -1A26, -1A26E1, - 1A26CJ, -1A29, -1A29CJ, -1A30, -1A32, -1A33, -1A33B2, and -1A35A turbofan engines with certain full authority digital engine control (FADEC) and prognostic health monitoring (PHM) software installed. This AD requires removing certain FADEC and PHM software and installing versions eligible for installation. This AD was prompted by aborted takeoffs after engines did not advance to the desired takeoff fan speed due to icing in the pressure sensor line. We are issuing this AD to address the unsafe condition on these products.
Airworthiness Directives; Hoffmann GmbH & Co. KG Propellers
We are adopting a new airworthiness directive (AD) for certain Hoffmann GmbH & Co. KG model HO-V 62 propellers. This AD was prompted by the failure of the propeller blade lag screws. This AD requires removal of the affected propeller blades and installation of modified propeller blades marked with change letter ``A'' or ``B.'' We are issuing this AD to address the unsafe condition on these products.
