August 20,2013

PROPOSED RULES

Airworthiness Directives; Eurocopter France Helicopters [FR DOC# 2013-20312] SUMMARY: We propose to adopt a new airworthiness directive (AD) for certain Eurocopter France (Eurocopter) Model AS332C, AS332L, AS332L1, AS332L2, and
SA330J helicopters. This proposed AD would require inspecting the crimping of the ball joint of the upper- and lower- end- fittings of the main servo-control and, depending on findings, replacing the main servo-control or repairing the ball joint. This proposed AD is prompted by incidents of missing crimping on the ball joints of servo-control end-fittings. The proposed actions are intended to prevent failure of a main servo-control upper end fitting, and subsequent failure of the flight controls and loss of control of the helicopter.

Airworthiness Directives; Airbus Airplanes [FR DOC# 2013-20251] SUMMARY: We propose to supersede airworthiness directive (AD) 2006-06- 14, that applies to certain Airbus Model A318-100 and A319-100 series airplanes, A320-111 airplanes, A320-200 series airplanes, and A321-100 and A321-200 series airplanes. AD 2006- 06-14 requires operators to review the airplane’s maintenance records to determine the part numbers of the magnetic fuel level indicators (MFLIs) of the wing fuel tanks, and related investigative and corrective actions if necessary. Since we issued AD 2006-06-14, we received information that the related investigative actions of the existing AD are not fully effective and that an affected MFLI could still be installed on airplanes on which the related investigative actions were accomplished. This proposed AD would also require an inspection (improved method) to determine the part numbers of the MFLIs, and, if necessary, replacement of the MFLI or repair. We are proposing this AD to prevent an ignition source in the wing fuel tank in the event of a lightning strike, which could result in a fire or explosion.

Airworthiness Directives; Piper Aircraft, Inc. [FR DOC# 2013-20328] SUMMARY: We propose to supersede an existing airworthiness directive (AD) that applies to certain Piper Aircraft, Inc. Models PA-28-140, PA- 28-150, PA-28-160, PA-28- 180, PA-28R-180, and PA-28R-200 airplanes. AD 71-21-08, Amendment 39-1312 (36 FR 19572, October 8, 1971) currently requires replacement of the fuel selector valve cover. Since we issued AD 71-21-08, it has been found that a similar fuel selector valve issue exists in additional serial numbered airplanes not identified in the existing AD. This proposed AD would add additional airplanes to the AD’s applicability section and changes the compliance time of the required actions. We are proposing this AD to correct the unsafe condition on these products.

Airworthiness Directives; Bell Helicopter Textron [FR DOC# 2013-20309] SUMMARY: We propose to supersede an existing airworthiness directive (AD) for Bell Helicopter Textron (Bell) Model 222, 222B, 222U, 230, and 430 helicopters. The existing AD currently requires inspecting parts of the main rotor hydraulic servo actuator (servo actuator) for certain conditions and replacing any unairworthy parts before further flight. Since we issued the AD, a new stainless steel piston rod has been manufactured. We propose requiring the installation of a servo actuator assembly with this piston rod and
setting an interval for the next overhaul at 10,000 hours time-in-service (TIS) or 10 years, whichever comes first. The proposed actions are intended to detect pitting or penetration of the base metal of the piston rod that could lead to the piston rod’s failure, the servo actuator’s failure, and the loss of helicopter control.

Airworthiness Directives; Bell Helicopter Textron, Inc. (Bell) Helicopters [FR DOC# 2013-20248] SUMMARY: We propose to adopt a new airworthiness directive (AD) for Bell Model 204B helicopters. This proposed AD would require inspecting the tail rotor (T/R) cable assembly for an incorrectly machined body. This proposed AD is prompted by a report from Bell that a defective body on the cable prevents the barrel assembly from fully engaging in the body cavity. The proposed actions are intended to prevent disengagement of the cable from the barrel, failure of the T/R pitch control, and subsequent loss of
control of the helicopter.

Airworthiness Directives; Various Restricted Category Helicopters [FR DOC# 2013-20249] SUMMARY: We propose to adopt a new airworthiness directive (AD) for various restricted category helicopters, originally manufactured by Bell Helicopter Textron, Inc. (Bell), model numbers HH-1K, TH-1F, TH- 1L, UH-1A, UH-1B, UH-1E, UH-1F, UH-1H, UH-1L, and UH-1P. The current type certificate holders include but are not limited to Arrow Falcon Exporters Inc.; AST, Inc.; Bell Helicopter Textron, Inc.; Global Helicopter Technology, Inc.; Hagglund Helicopters, LLC; International Helicopters, Inc.; JJASPP Engineering Services, LLC; Northwest Rotorcraft, LLC; OAS Parts LLC; Richards Heavylift Helo, Inc.; Robinson Air Crane, Inc.; Rotorcraft Development Corporation; San Joaquin Helicopters; Smith Helicopters; Southern Helicopter, Inc.; Southwest Florida Aviation International, Inc.; Tamarack Helicopters, Inc; and Southwest Florida Aviation, Inc. This proposed AD would require inspecting the tail rotor (T/R) cable assembly for an incorrectly machined body. This proposed AD is prompted by a report from Bell that a defective body on the cable prevents the barrel assembly from fully engaging in
the body cavity. The proposed actions are intended to prevent disengagement of the cable from the barrel, failure of the T/R pitch control, and subsequent loss of control of the helicopter.

RULES

Airworthiness Directives; Airbus Airplanes [FR DOC# 2013-20105] SUMMARY: We are superseding airworthiness directive (AD) 2004-13-06 for certain Airbus Model A319 and A320 series airplanes. AD 2004-13-06 required repetitive detailed inspections to detect cracks in the keel beam side panels, and repair if necessary. This new AD requires repetitive eddy current inspections for cracking in the keel beam side panels, and corrective actions if necessary. This AD was prompted by reports of cracks on the side panels of the keel beams. We are issuing this AD to detect and correct fatigue cracks on
the side panels of the keel beams, which could result in reduced structural integrity of the airplane.

Airworthiness Directives; Eurocopter France Helicopters [FR DOC# 2013-19159] SUMMARY: We are adopting a new airworthiness directive (AD) for certain Eurocopter France (Eurocopter) Model AS332C, AS332L, AS332L1, AS332L2, and EC225LP helicopters to require inspecting for the presence of blind holes in the tailgearbox (TGB) attachment fittings, and, if they are missing, installing an additional washer under the head of the attachment bolt until the attachment fitting is replaced with an airworthy attachment fitting. This AD was prompted by the discovery of interference between the TGB aft attachment bolt and the structure fitting, caused by a manufacturing anomaly that omitted the blind hole required for proper fit of the attachment bolt. This condition, if not detected and corrected, could result in insufficient tightening of the TGB casing, damage to the TGB attachment, cracking under the attachment bolt, and loss of the TGB, resulting in loss of control of the helicopter.

Airworthiness Directives; Bombardier, Inc. Airplanes [FR DOC# 2013-19157] SUMMARY: We are adopting a new airworthiness directive (AD) for certain Bombardier, Inc. Model DHC-8-102, -103, and -106 airplanes. This AD was prompted by a report of cracking in a lower longeron in a nacelle. This AD requires repetitive inspections for cracking of the
lower longerons in the nacelles, and replacement with new longerons or repair if necessary. Additionally, this AD specifies an optional terminating action. We are issuing this AD to detect and correct such cracking, which could result in degradation of the structural integrity of the nacelle and possible collapse of the main landing gear (MLG).

Airworthiness Directives; Beechcraft Corporation and Hawker Beechcraft Corporation [FR DOC# 2013-20098] SUMMARY: We are adopting a new airworthiness directive (AD) for certain Beechcraft Corporation (type certificate previously held by Hawker Beechcraft Corporation) Models 58, 95-C55, E55, and 56TC airplanes; and Hawker Beechcraft Corporation Models 58P and 58TC airplanes (both type certificates previously held by Raytheon Aircraft Company). This AD was prompted by reports of elevator balance weights becoming loose or failing because the balance weight material was under strength and did not meet material specifications. This AD requires inspections of elevator balance weights and replacement of defective elevator balance weights. We are issuing this AD to correct the unsafe condition on these products.

Airworthiness Directives; Bombardier, Inc. Airplanes [FR DOC# 2013-20109] SUMMARY: We are adopting a new airworthiness directive (AD) for certain Bombardier, Inc. Model CL-600-2C10 (Regional Jet Series 700, 701, & 702) airplanes, Model CL-600-2D15 (Regional Jet Series 705) airplanes, and Model CL-600-2D24 (Regional Jet Series 900) airplanes. This AD was prompted by a report of corrosion of the components of the main landing gear (MLG) retraction actuator found in service; the corrosion was found at the interface of the rod end and the piston, and at the bracket and related pins. This AD requires inspection of the MLG retraction actuator components; corrective actions if necessary; and, for certain retraction actuators, installation of a new jam nut. We are issuing this AD to prevent disconnection of the MLG retraction actuator, which could result in extension of the MLG without damping, and consequent structural damage and
collapse of the MLG during landing.
