Special Conditions: Boeing Model 787-8 Airplane; Lithium Ion Battery Installation
Document Number: E7-8186
Type: Proposed Rule
Date: 2007-04-30
Agency: Federal Aviation Administration, Department of Transportation
This notice proposes special conditions for the Boeing Model 787-8 airplane. This airplane will have novel or unusual design features when compared to the state of technology envisioned in the airworthiness standards for transport category airplanes. The Boeing Model 787-8 airplanes will use high capacity lithium ion battery technology in on-board systems. For this design feature, the applicable airworthiness regulations do not contain adequate or appropriate safety standards. These proposed special conditions contain the additional safety standards that the Administrator considers necessary to establish a level of safety equivalent to that established by the existing airworthiness standards. Additional special conditions will be issued for other novel or unusual design features of the Boeing Model 787-8 airplanes.

Airworthiness Directives; McDonnell Douglas Model 717-200 Airplanes
Document Number: E7-8176
Type: Proposed Rule
Date: 2007-04-30
Agency: Federal Aviation Administration, Department of Transportation
The FAA is revising an earlier proposed airworthiness directive (AD) for certain McDonnell Douglas Model 717-200 airplanes. The original NPRM would have required modifying the fuel boost pump container of the center tank. The original NPRM resulted from fuel system reviews conducted by the manufacturer. This action revises the original NPRM by adding airplanes to the applicability. We are proposing this supplemental NPRM to prevent exposing the fuel pump container vapor area to electrical arcing during a fuel pump motor case or connector burn through, which could result in a fuel tank explosion.
Airworthiness Directives; Boeing Model 767 Airplanes
Document Number: E7-8175
Type: Proposed Rule
Date: 2007-04-30
Agency: Federal Aviation Administration, Department of Transportation
The FAA proposes to adopt a new airworthiness directive (AD) for certain Boeing Model 767 airplanes. This proposed AD would require sealing certain fasteners and stiffeners in the fuel tank, and changing certain wire bundle clamp configurations on the fuel tank walls. This proposed AD results from fuel system reviews conducted by the manufacturer. We are proposing this AD to prevent possible ignition sources in the auxiliary fuel tank, main fuel tanks, and surge tanks caused by a wiring short or lightning strike, which could result in fuel tank explosions and consequent loss of the airplane.
Aviation Proceedings, Agreements Filed the Week Ending April 20, 2007

Airworthiness Directives; Airbus Model A330 and A340 Airplanes
Document Number: E7-8172
Type: Proposed Rule
Date: 2007-04-30
Agency: Federal Aviation Administration, Department of Transportation
We propose to adopt a new airworthiness directive (AD) for the products listed above. This proposed AD results from mandatory continuing airworthiness information (MCAI) issued 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 failure of an evacuation slide raft to inflate, which could delay the evacuation of passengers in case of an emergency. The proposed AD would require actions that are intended to address the unsafe condition described in the MCAI.
Airworthiness Directives; M7 Aerospace LP SA226 and SA227 Series Airplanes
Document Number: E7-8163
Type: Proposed Rule
Date: 2007-04-30
Agency: Federal Aviation Administration, Department of Transportation
We propose to supersede Airworthiness Directive (AD) 98-19-15 R1 and AD 2000-03-17, which apply to M7 Aerospace LP SA226 and SA227 series airplanes equipped with certain pitch trim actuators. AD 98-19- 15 R1 currently requires you to incorporate changes into the Limitations Section of the FAA-approved Airplane Flight Manual (AFM) if certain part number (P/N) pitch trim actuators are installed. AD 2000- 03-17 requires repetitive inspections and repetitive replacements of the pitch trim actuator. The repetitive inspection and repetitive replacement times vary depending on the combination of airplane model and pitch trim actuator P/N installed. We are proposing this AD because we have determined that reliance on critical repetitive inspections on aging commuter-class airplanes carries an unnecessary safety risk when a design change exists that could eliminate or, in certain instances, reduce the number of those critical inspections. Consequently, this proposed AD would retain all of the actions of the previously referenced ADs, place life limits on certain P/N pitch trim actuators, and require the replacement of certain P/N pitch trim actuators with one of an improved design. Once installed, the improved design pitch trim actuator would terminate the AFM limitations in this proposed AD and reduce the repetitive inspection and repetitive replacement requirements. We are proposing this AD to detect excessive freeplay or rod slippage in the pitch trim actuator, which, if not detected and corrected, could result in pitch trim actuator failure. We are also proposing this AD to lessen the severity of pitch upset if a pitch trim actuator mechanical failure occurs. These conditions could lead to possible loss of control.

Airworthiness Directives; Boeing Model 777-200, 777-300, and 777-300ER Series Airplanes
Document Number: E7-7853
Type: Rule
Date: 2007-04-30
Agency: Federal Aviation Administration, Department of Transportation
The FAA is adopting a new airworthiness directive (AD) for certain Boeing Model 777-200, 777-300, and 777-300ER series airplanes. This AD requires repetitive inspections for discrepancies of the splined components that support the inboard end of the inboard trailing edge flap; related investigative, corrective, and other specified actions if necessary; a one-time modification of the inboard support of the inboard trailing edge flap by installing a new isolation strap and attachment hardware; and repetitive replacement of the torque tube assembly. For certain Boeing Model 777-200 series airplanes, this AD also specifies prior or concurrent accomplishment of one-time inspections of the flap seal panels for cracking and minimum clearances, and of the torque tubes for damage; and related investigative and corrective actions if necessary. This AD also provides a terminating action (modification of the inboard main flap) for the repetitive inspections. This AD results from reports of corrosion on the torque tube and closeout rib fittings that support the inboard end of the inboard trailing edge flap, as well as a structural reassessment of the torque tube joint that revealed the potential for premature fatigue cracking of the torque tube that would not be detected using reasonable inspection methods. We are issuing this AD to detect and correct corrosion or cracking of the torque tube and closeout rib fittings that support the inboard end of the inboard trailing edge flap. Cracking in these components could lead to a fracture, which could result in loss of the inboard trailing edge flap and consequent reduced controllability of the airplane.
Airworthiness Directives; Boeing Model 737-800 Series Airplanes
Document Number: E7-7850
Type: Rule
Date: 2007-04-30
Agency: Federal Aviation Administration, Department of Transportation
This document publishes in the Federal Register an amendment adopting airworthiness directive (AD) 2007-06-52 that was sent previously to all known U.S. owners and operators of Boeing Model 737- 800 series airplanes by individual notices. This AD requires inspecting spoilers to determine spoiler position after every landing and after any rejected takeoff maneuvers. For airplanes on which any spoiler is found in the up position with the speedbrake handle in the down position, this AD requires replacement of the flight spoiler actuator with a flight spoiler actuator having a certain part number. This AD also requires an operational test of the speedbrake control system after any maintenance actions that operate the spoiler system and replacement of the flight spoiler actuator if necessary. This AD also provides for optional terminating action for those requirements. In addition, this AD requires you to report to the manufacturer any spoiler panel that is found in the up position with the speedbrake handle in the down position. This AD results from a report of seven flight spoiler actuator jams on Model 737-800 Short Field Performance airplanes. We are issuing this AD to detect and correct any spoiler panel that is found in the up position with the speedbrake handle in the down position, which could result in a spoiler actuator hardover, and could cause the spoiler surface to jam in the fully extended position. Two or more hardover failures of the spoiler surfaces in the up direction on the same wing, if undetected prior to takeoff, can cause significant roll and consequent loss of control of the airplane.
Airworthiness Directives; Empresa Brasileira de Aeronautica S.A. (EMBRAER) Model ERJ 170 and ERJ 190 Airplanes
Document Number: E7-7841
Type: Rule
Date: 2007-04-30
Agency: Federal Aviation Administration, Department of Transportation
This document publishes in the Federal Register an amendment adopting airworthiness directive (AD) 2007-06-53 that was sent previously to all known U.S. owners and operators of EMBRAER Model ERJ 170 and ERJ 190 airplanes by individual notices. This AD requires repetitively verifying the correct closure of the forward and aft cargo doors, inspecting the forward and aft cargo doors for interference between the lock handle and the aft edge liner assembly, repetitively inspecting the lateral roller fittings on the forward and aft cargo door frames for damage, and doing corrective actions if needed. This AD also requires reporting any signs of interference or damage to the manufacturer. This AD results from a report indicating that the aft cargo door opened in flight just after departure, and from a report indicating that an airplane was dispatched with an unsecured forward cargo door. We are issuing this AD to prevent a cargo door from opening during flight, which could lead to structural failure or loss of control.

Document Number: E7-7979
Type: Proposed Rule
Date: 2007-04-26
Agency: Federal Aviation Administration, Department of Transportation
The FAA is revising an earlier NPRM for an airworthiness directive (AD) that applies to certain Bombardier Model CL-600-1A11 (CL-600) airplanes, CL-600-2A12 (CL-601) airplanes, and CL-600-2B16 (CL-601-3A, CL-601-3R, and CL-604) airplanes. The original NPRM would have required inspecting to identify the part number and serial number of the selector valves of the nose landing gear (NLG) and the nose gear door; and doing related investigative and corrective actions if necessary. The original NPRM resulted from reports of uncommanded partial retractions of the NLG. This action revises the original NPRM by adding airplanes to the applicability. We are proposing this supplemental NPRM to prevent internal leakage of the selector valve, which, under certain conditions, could result in an uncommanded retraction of the NLG with consequent damage to the airplane and possible serious injury to ground personnel.
Airworthiness Directives; Boeing Model 747-100, 747-100B, 747-100B SUD, 747-200B, 747-200C, 747-300, 747-400, 747-400D, and 747SR Series Airplanes
Document Number: E7-7978
Type: Proposed Rule
Date: 2007-04-26
Agency: Federal Aviation Administration, Department of Transportation
The FAA proposes to supersede an existing airworthiness directive (AD) that applies to all Boeing Model 747-100, 747-100B, 747- 100B SUD, 747-200B, 747-200C, 747-300, 747-400, 747-400D, and 747SR series airplanes. The existing AD currently requires repetitive inspections for cracking of the station 800 frame assembly, and repair if necessary. This proposed AD would revise certain applicabilities and compliance times in the existing AD. This proposed AD results from several reports of cracks of the station 800 frame assembly on airplanes that had accumulated fewer total flight cycles than the initial inspection threshold in the original AD. We are proposing this AD to detect and correct fatigue cracks that could extend and fully sever the frame, which could result in development of skin cracks that could lead to rapid depressurization of the airplane.

This notice proposes special conditions for the Boeing Model 787-8 airplane. This airplane will have novel or unusual design features when compared to the state of technology envisioned in the airworthiness standards for transport category airplanes. The fuselage of the Boeing Model 787-8 series airplane will be made of composite materials rather than conventional aluminum. While the regulations include flame propagation standards for some materials commonly found in inaccessible areas of the airplane, they do not yet incorporate standards for materials used to construct the fuselage. Therefore, special conditions are needed to address this design feature. These proposed special conditions contain the additional safety standards that the Administrator considers necessary to establish a level of safety equivalent to that established by the existing airworthiness standards. Additional special conditions will be issued for other novel or unusual design features of the Boeing Model 787-8 airplanes.

The FAA is adopting a new airworthiness directive (AD) for certain Learjet Model 45 airplanes. This AD requires deactivating the auxiliary power unit (APU), capping/plugging the fuel lines to the APU, and removing the APU fuel shutoff valve. This AD results from reports of fuel leaking from the APU fuel shutoff valve into a flammable fluid fire protection area that is also interconnected with the main landing gear's wheel well bay. We are issuing this AD to prevent fuel leaking from the fuel shutoff valve of the APU, which could result in an uncontrollable fire and adversely affect the airplane's continued safe flight and landing.
