Aviation Rulemaking Advisory Committee Meeting on Transport Airplane and Engine Issues
Document Number: 2012-9954
Type: Notice
Date: 2012-04-25
Agency: Federal Aviation Administration, Department of Transportation
This notice announces a public meeting of the FAA's Aviation Rulemaking Advisory Committee (ARAC) to discuss transport airplane and engine (TAE) issues.
Airworthiness Directives; The Boeing Company Airplanes
Document Number: 2012-9916
Type: Proposed Rule
Date: 2012-04-25
Agency: Federal Aviation Administration, Department of Transportation
We propose to adopt a new airworthiness directive (AD) for certain Boeing Company Model 757 airplanes. This proposed AD was prompted by a report of in-flight fracture of the right windshield (window 1) on the flight deck and multiple reports of electrical arcs at the terminal blocks of the flight deck windshields resulting in smoke and fire. This proposed AD would require repetitive inspections of electrical heat terminals on the left and right windshields for damage, and corrective actions if necessary. This proposed AD would also allow for replacing an affected windshield with a windshield equipped with different electrical connections, which would terminate the repetitive inspections for that windshield. We are proposing this AD to prevent smoke and fire in the flight deck, which can lead to loss of visibility, and injuries to or incapacitation of the flight crew.
Airworthiness Directives; Turbomeca S.A. Turboshaft Engines
Document Number: 2012-9789
Type: Rule
Date: 2012-04-25
Agency: Federal Aviation Administration, Department of Transportation
We are adopting a new airworthiness directive (AD) for all Turbomeca S.A. Arriel 2B and 2B1 turboshaft engines. This AD was prompted by the discovery of non-conformities of certain power turbine (PT) blade fir-tree roots. This AD requires removing the affected PT blades from service on or before reaching a new reduced life limit for those certain PT blades. We are issuing this AD to prevent PT blade rupture, which could result in an uncommanded in-flight engine shutdown, forced autorotation landing, or accident.
