Aviation Fuel and Oil Operating Limitations; Policy Memorandum
This document announces the issuance of policy memorandum for Aviation Fuel and Oil Operating Limitations. This policy memorandum provides guidance for Aircraft Certification Offices (ACOs) and the Engine Certification Office (ECO) when evaluating compliance with the standards for aviation fuel and oil operating limitations. This policy does not create any new requirements, and is not specifically limited to new model type certification.
Airworthiness Directives; The Boeing Company Model 737-100, -200, -200C, -300, -400, and -500 Series Airplanes
We propose to supersede an existing airworthiness directive (AD) that applies to certain Model 737-100 and -200 series airplanes. The existing AD currently requires various inspections for cracks in the outboard chord of the frame at body station (BS) 727 and in the outboard chord of stringer (S) 18A, and repair or replacement of cracked parts. Since we issued that AD, there have been several reports of fatigue cracking in the frame outboard chord at BS 727 and in the radius of the auxiliary chord on airplanes that were not affected by the existing AD. This proposed AD would add airplanes to the applicability statement in the existing AD and add inspections for cracks in the BS 727 frame outboard chords and the radius of the auxiliary chord, for certain airplanes. This proposed AD would also remove the inspections of the outboard chord of S-18A required by the existing AD. We are proposing this AD to detect and correct fatigue cracking of the outboard and auxiliary chords, which could result in reduced structural integrity of the outboard chord and consequent rapid decompression of the airplane.
Airworthiness Directives; ATR-GIE Avions de Transport Régional Model ATR42 and ATR72 Airplanes
We propose to adopt a new airworthiness directive (AD) for the products listed above. 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 describes the unsafe condition as:
Airworthiness Directives; Dassault Aviation Model FALCON 7X Airplanes
We are adopting a new airworthiness directive (AD) for the products listed above that would supersede an existing AD. This 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 describes the unsafe condition as:
Airworthiness Directives; The Boeing Company Model 747-400 and -400F Series Airplanes
We are adopting a new airworthiness directive (AD) for the products listed above. This AD requires a general visual inspection for cracks and holes of the main equipment center (MEC) drip shields, and repairs if necessary; installation of a fiberglass reinforcing overcoat; and, for certain airplanes, installation of stiffening panels to the MEC drip shields. This AD was prompted by a report of a loss of bus control unit number 1 and generator control units numbers 1 and 2 while the airplane was on the ground, and multiple operator reports of cracked MEC drip shields. We are issuing this AD to prevent water penetration into the MEC, which could result in the loss of flight critical systems.
Modification of Class E Airspace; Forsyth, MT
This action will modify Class E airspace at Forsyth, MT. Controlled airspace is necessary to accommodate aircraft using Area Navigation (RNAV) Global Positioning System (GPS) standard instrument approach procedures at Tillitt Field Airport. This action also corrects a typographical error in the regulatory text for the Class E airspace area. This action improves the safety and management of Instrument Flight Rules (IFR) operations at the airport.
Airworthiness Directives; Airbus Model A300 B4-600, A300 B4-600R, and A300 F4-600R Series Airplanes, and Model A300 C4-605R Variant F Airplanes (Collectively Called Model A300-600 Series Airplanes); Model A310 Series Airplanes; Model A318 Series Airplanes; Model A319 Series Airplanes; Model A320-211, -212, -214, -231, -232, and -233 Airplanes; Model A321 Series Airplanes; Model A330-200 and A330-300 Series Airplanes; and Model A340-200, A340-300, A340-500, and A340-600 Series Airplanes
We are adopting a new airworthiness directive (AD) for the products listed above. This 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. For Model A310 and A300-600 series airplanes, the MCAI describes the unsafe condition as:
