Federal Register Proposed Rules, Rules and Notices for May 30,2013

May 30,2013

PROPOSED RULES

Airworthiness Directives; PIAGGIO AERO INDUSTRIES S.p.A Airplanes [FR DOC# 2013-12822] SUMMARY: We propose to rescind an airworthiness directive (AD) for PIAGGIO AERO INDUSTRIES S.p.A. Model P-180 airplanes. The existing AD resulted 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 partial detachment of the inner protective film of the composite nacelles. Since issuance of that AD, we have determined that the unsafe condition does not exist or is not likely to develop on affected type design airplanes, and therefore the AD should be rescinded. The proposed AD would allow the public the opportunity to comment on the FAA’s determination of the unsafe condition no longer existing before it is officially rescinded.

 
RULES

Airworthiness Directives; Airbus Airplanes [FR DOC# 2013-12515] SUMMARY: We are adopting a new airworthiness directive (AD) for all Airbus Model A300 B4-601, B4-603, B4-620, B4- 605R, and B4-622R airplanes. This AD was prompted by a report that the door frame shells of passenger doors 2 and 4 may not have sufficient structural strength to enable the airplane to operate safely. This AD requires reinforcing the door frame shells of
passenger doors 2 and 4 on both sides of the fuselage. We are issuing this AD to prevent
structural failure of the door frame shells, which could result in in-flight
decompression of the airplane and consequent injury to passengers.

Airworthiness Directives; Airbus Airplanes [FR DOC# 2013-12519] SUMMARY: We are adopting a new airworthiness directive (AD) for all Airbus Model A330-200 Freighter, A330-200, A330-300, A340-200, A340- 300, A340-500, and A340-600 series airplanes. This AD was prompted by several reports of a burning smell and/or smoke in the cockpit during cruise phase leading, in some cases, to diversion to alternate airports. This AD requires an inspection to identify the installed windshields and replacement of any affected windshield. We are issuing this AD to prevent significantly increased workload for the flightcrew, which could, under some flight phases and/or circumstances, constitute an unsafe condition.

Airworthiness Directives; Cessna Aircraft Company Airplanes [FR DOC# 2013-12662] SUMMARY: We are adopting a new airworthiness directive (AD) for certain Cessna Aircraft Company Model 500, 501, 550, 551, S550, 560, 560XL, and 650 airplanes. This AD was prompted by multiple reports of smoke and/or fire in the tailcone caused by sparking due to excessive wear of the brushes in the air conditioning (A/C) motor. This AD requires inspecting to determine if certain A/C compressor motors are installed and to determine the accumulated hours on certain A/C drive motor assemblies; repetitive replacement of the brushes in the drive motor assembly, or, as an option to the brush replacement, deactivation of the A/C system and placard installation; and return of replaced brushes to Cessna. We are issuing this AD to prevent the brushes in the A/C motor from wearing down beyond their limits, which could result in the rivet in the brush contacting the commutator causing sparks and consequent fire and/or smoke in the tailcone with no means to detect or extinguish the fire and/or smoke.

Airworthiness Directives; Bombardier, Inc. Airplanes [FR DOC# 2013-12615] SUMMARY: We are adopting a new airworthiness directive (AD) for certain Bombardier, Inc. Model CL-215- 1A10 and CL-215-6B11 (CL-215T Variant) airplanes. This AD requires repetitive detailed inspections for cracking of the left-hand (LH) and right-hand (RH) wing lower skin, and repair if necessary. This AD also provides terminating action for the repetitive detailed inspections. This AD was prompted by reports of a fractured wing lower rear spar cap and reinforcing strap. We are issuing this AD to detect and correct cracked wing structure, which could result in failure of the wing.

Establishment of Class E Airspace; Bass Harbor, ME [FR DOC# 2013-12705] SUMMARY: This action establishes Class E Airspace at Bass Harbor, ME, to accommodate a new Area
Navigation (RNAV) Global Positioning System (GPS) special Standard Instrument Approach Procedure (SIAP) serving Bass Harbor Heliport. This action enhances the safety and airspace management of Instrument Flight Rules (IFR) operations within the National
Airspace System. Also, geographic coordinates are corrected under their proper heading.
