Clarification of Parachute Packing Authorization
This action amends the requirements for individuals who pack, maintain, or alter main parachutes of a dual-parachute systemthose with main and ``back up'' parachutesto be used for parachute jumping in connection with civil aircraft of the United States. It expressly limits the authority of a non-certificated person who is not under the supervision of an appropriate current certificated parachute rigger to only pack the main parachute of a dual-parachute system when that person will be the next jumper to use the parachute. This action is intended to correct a potentially unsafe condition of parachute operations created by changes to the 2001 revision of the current rule.
Executive Committee of the Aviation Rulemaking Advisory Committee; Meeting
The FAA is issuing this notice to advise the public of a meeting of the Executive Committee of the Aviation Rulemaking Advisory Committee.
Airworthiness Directives; Pratt & Whitney PW4000 Series Turbofan Engines
The FAA proposes to adopt a new airworthiness directive (AD) for Pratt & Whitney PW4000 series turbofan engines. This proposed AD would require a one-time visual inspection of the No. 3 bearing oil pressure tube, part number (P/N) 51J041-01, P/N 50J604-01, or P/N 50J924-01. Tubes that are found cracked or repaired would be required to be removed from service. This proposed AD would also prohibit repaired tubes from being installed. This proposed AD results from one report of a repaired No. 3 bearing oil tube that caused an engine in- flight shutdown, seven reports of repaired No. 3 bearing oil pressure tubes found cracked that led to unscheduled engine removals, and one report of a test cell event from a repaired tube that cracked. We are proposing this AD to prevent cracking of No. 3 bearing oil pressure tubes which could result in internal oil fire, failure of the high- pressure turbine (HPT) disks, uncontained engine failure, and damage to the airplane.
Airworthiness Directives; The Boeing Company Model 757 Airplanes
We propose to adopt a new airworthiness directive (AD) for all Model 757 airplanes. This proposed AD would require changing the lower fixed leading edge panel assemblies immediately outboard of the nacelles at slats 4 and 7. This proposed AD results from reports of Model 757 airplanes in service that have drain holes and unsealed panel assemblies in the fixed leading edge adjacent to the inboard end of slats 4 and 7 that are too close to the hot portion of the engines. We are proposing this AD to prevent fuel leaking onto an engine and a consequent fire.
Airworthiness Directives; The Boeing Company Model 757 Airplanes
We propose to adopt a new airworthiness directive (AD) for all Model 757 airplanes. This proposed AD would require a detailed inspection of the inboard and outboard main track downstop assemblies and a torque application to the main track downstop assembly nuts of slat numbers 1 through 10, excluding the outboard track of slats 1 and 10, a detailed inspection of all slat track housings, and related corrective actions if necessary. This proposed AD results from reports of fuel leaking from the front spar of the wing through the slat track housing. We are proposing this AD to detect and correct incorrectly installed main track downstop assemblies, which, when the slat is retracted, could cause a puncture in the slat track housing leading to a fuel leak and potential fire.
Airworthiness Directives; Bombardier, Inc. Model CL-600-2B19 (Regional Jet Series 100 & 440) 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: There have been several Stick Pusher Capstan Shaft failures causing severe degradation of the stick pusher function. This directive is issued to revise the first flight of the day check of the stall protection system to detect degradation of the stick pusher function. It also introduces a new repetitive maintenance task to limit exposure to dormant failure of the stick pusher capstan shaft. Dormant loss or severe degradation of the stick pusher function could result in reduced controllability of the airplane. The proposed AD would require
Airworthiness Directives; Empresa Brasileira de Aeronautica S.A. (EMBRAER) Model EMB-120, -120ER, -120FC, -120QC, and -120RT 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: It has been found that some fuel quantity probes may fail during the airplane life leading to an erroneous fuel quantity indication to the crew. This erroneous indication may lead to the airplane being operated with less fuel than indicated which may lead to an uncommanded in-flight shutdown of one or both engines due to fuel starvation. The proposed AD would require actions that are intended to
Airworthiness Directives; Airbus Model A319-100, A320-200, A321-100, and A321-200 Series Airplanes
The FAA is correcting a typographical error in an existing airworthiness directive (AD) that was published in the Federal Register on May 12, 2006. The error resulted in an incorrect component maintenance manual number. This AD applies to certain Airbus Model A319-100, A320-200, A321-100, and A321-200 series airplanes. This AD requires repetitive inspections for corrosion in the inside and outside lower walls of each type A, D, E, and F lavatory wall that has at least one wall-mounted cabin attendant seat, and related investigative and corrective actions if necessary.
