Airworthiness Directives; The Boeing Company Airplanes
We propose to adopt a new airworthiness directive (AD) for all The Boeing Company Model 707 airplanes and Model 720 and 720B series airplanes. This proposed AD was prompted by a determination that undetected web fatigue cracking caused by oil canning may exist in the station 1440 aft pressure bulkhead web. This proposed AD would require repetitive detailed inspections for any oil canning or cracking of the station 1440 aft pressure bulkhead web, and related corrective actions if necessary. We are proposing this AD to address the unsafe condition on these products.
Airworthiness Directives; Dassault Aviation Airplanes
We propose to supersede Airworthiness Directive (AD) 2013-03- 12 for all Dassault Aviation Model MYSTERE-FALCON 50 airplanes. AD 2013-03-12 currently requires revising the maintenance program to incorporate new or revised maintenance requirements and airworthiness limitations. Since we issued AD 2013-03-12, the manufacturer has issued a revision to the airplane maintenance manual (AMM) that introduces new or more restrictive maintenance requirements and/or airworthiness limitations. This proposed AD would require revising the maintenance or inspection program, as applicable, to incorporate new or revised maintenance requirements and airworthiness limitations. We are proposing this AD to prevent reduced structural integrity of the airplane.
Airworthiness Directives; Airbus Airplanes
We propose to supersede Airworthiness Directive (AD) 2007-13- 08, for certain Airbus Model A318, A319, A320, and A321 series airplanes. AD 2007-13-08 currently requires repetitive inspections of the auxiliary power unit (APU) starter motor, APU inlet plenum, and APU air intake for discrepancies; repetitive cleaning of the APU air intake, and applicable corrective actions. Since we issued AD 2007-13- 08, a determination was made that the unsafe condition could occur on additional airplanes. This proposed AD would expand the applicability in AD 2007-13-08, and include an optional terminating installation for the repetitive actions. We are proposing this AD to address the unsafe condition on these products.
Airworthiness Directives; Dassault Aviation Airplanes
We are adopting a new airworthiness directive (AD) for all Dassault Aviation Model FAN JET FALCON airplanes; Model FAN JET FALCON SERIES C, D, E, F, and G airplanes; Model MYSTERE-FALCON 200 airplanes; Model MYSTERE-FALCON 20-C5, 20-D5, 20-E5, and 20-F5 airplanes; and MYSTERE-FALCON 50 airplanes. This AD was prompted by a report that, during approach for landing, the main entry door detached from an airplane. This AD requires a functional test or check of the main entry door closure and warning system, and applicable door closing inspections, adjustments, operational tests, and corrective actions if necessary. We are issuing this AD to address the unsafe condition on these products.
Airworthiness Directives; Airbus Airplanes
We are adopting a new airworthiness directive (AD) for certain Airbus Model A330-200 Freighter, -200 and -300 series airplanes; and Airbus Model A340-200, -300, -500, and -600 series airplanes. This AD was prompted by reports of certain hydraulic reservoirs (HRs) becoming depressurized due to air leakage from the HR pressure relief valve (PRV). This AD requires repetitive inspections of the hydraulic fluid levels and nitrogen gas pressure in the HR for each hydraulic circuit, and if necessary, adjustment of the fluid level(s) and nitrogen pressure in affected HRs. We are issuing this AD to address the unsafe condition on these products.
