Airworthiness Directives; BURKHARDT GROB LUFT-UND RAUMFAHRT GmbH & CO KG Models G103 TWIN ASTIR, G103 TWIN II, G103A TWIN II ACRO, G103C TWIN III ACRO, and G103C Twin III SL Sailplanes
Document Number: 05-19942
Type: Proposed Rule
Date: 2005-10-05
Agency: Federal Aviation Administration, Department of Transportation
The FAA proposes to supersede Airworthiness Directive (AD) 2004-08-13, which applies to certain BURKHARDT GROB LUFT-UND RAUMFAHRT GmbH & CO KG (Grob) Models G103 TWIN ASTIR, G103 TWIN II, G103 TWIN III ACRO, and G103C Twin III SL sailplanes. AD 2004-08-13 currently requires you to replace the center of gravity (CG) release hook attachment brackets with brackets of improved design. This proposed AD results from mandatory continuing airworthiness information (MCAI) issued by the airworthiness authority for Germany. This proposed AD would retain all the actions required in AD 2004-08-13 and add Model G103A TWIN II ACRO sailplanes to the applicability. The actions specified by this proposed AD are to prevent abnormal or uncontrolled sailplane release due to cracked CG release hook attachment brackets. This condition could result in reduced or loss of sailplane control.
Airworthiness Directives; Engine Components Incorporated (ECi) Reciprocating Engine Connecting Rods
Document Number: 05-19940
Type: Proposed Rule
Date: 2005-10-05
Agency: Federal Aviation Administration, Department of Transportation
The FAA proposes to adopt a new airworthiness directive (AD) for certain Lycoming Engines (formerly Textron Lycoming) 360 and 540 series reciprocating engines with ECi connecting rods, part number (P/ N) AEL 11750, installed. This proposed AD would require replacing certain serial-numbered connecting rods, P/N AEL 11750. This proposed AD would also prohibit installing certain ECi connecting rods, P/N AEL 11750 into any Lycoming 360 or 540 series reciprocating engines. This proposed AD results from reports of connecting rods with excessive variation in circularity of the journal bores. We are proposing this AD to prevent fatigue failure of the connecting rod and uncommanded shutdown of the engine.
Airworthiness Directives; Boeing Model 767-200, -300, and -300F Series Airplanes
Document Number: 05-19939
Type: Rule
Date: 2005-10-05
Agency: Federal Aviation Administration, Department of Transportation
The FAA is revising an existing airworthiness directive (AD) that applies to all Boeing Model 767-200, -300, and -300F series airplanes. The existing AD currently requires inspections to detect cracking or corrosion of the fail-safe straps between the side fitting of the rear spar bulkhead at body station 955 and the skin; and follow- on/corrective actions. The existing AD results from reports of cracked and/or corroded fail-safe straps at body station (BS) 955 on Boeing Model 767-200 series airplanes. We issued the existing AD to detect and correct fatigue cracking or corrosion of the fail-safe straps, which could result in cracking of adjacent structure and consequent reduced structural integrity of the fuselage. This new AD revises the applicability of the existing AD to reduce the number of affected airplanes. We are issuing this AD to detect and correct fatigue cracking or corrosion of the fail-safe straps, which could result in cracking of adjacent structure and consequent reduced structural integrity of the fuselage.
Airworthiness Directives; Honeywell Flight Management System (FMS) One Million Word (1M or 700K) Data Bases (9104 Cycle or Earlier), as Installed in, but Not Limited to, McDonnell Douglas Model MD-11 and MD-11F Airplanes, Boeing Model 747-400 Series Airplanes, and Boeing Model 757 and 767 Airplanes
Document Number: 05-19938
Type: Rule
Date: 2005-10-05
Agency: Federal Aviation Administration, Department of Transportation
The FAA is rescinding an existing airworthiness directive (AD) that applies to Honeywell FMS one million word (1M or 700K) data bases (9104 cycle or earlier) as installed in, but not limited to McDonnell Douglas Model MD-11 and MD-11F airplanes, Boeing Model 747-400 series airplanes, and Boeing Model 757 and 767 airplanes. That AD requires a revision to the FAA-approved Airplane Flight Manual (AFM) and installation of a placard to prohibit the use of Nondirectional Beacon (NDB) approaches for landing. That AD was prompted by an anomaly in the Honeywell FMS one million word (1M or 700K) data bases (9104 cycle or earlier). We issued that AD to prevent an airplane deviating from the published approach to the runway, which could lead to premature ground contact before reaching the runway. Since we issued that AD, we have determined that the Honeywell FMS one million word (1M or 700K) databases (9104 cycle or earlier) no longer exist on any of the affected airplanes.
Airworthiness Directives; DG Flugzeugbau GmbH Models DG-800B and DG-500MB Sailplanes
Document Number: 05-19936
Type: Proposed Rule
Date: 2005-10-05
Agency: Federal Aviation Administration, Department of Transportation
The FAA proposes to adopt a new airworthiness directive (AD) for certain DG Flugzeugbau GmbH Models DG-800B and DG-500MB sailplanes. This proposed AD would require you to modify the connection of the starter ring gear to the lower drive belt pulley adapter. This proposed AD results from mandatory continuing airworthiness information (MCAI) issued by the airworthiness authority for Germany. We are issuing this proposed AD to prevent the bolts currently used to connect the starter ring gear to the drive belt pulley adapter from shearing off and the bolt heads falling into the engine compartment. Failure of this connection could render the engine inoperative. Consequently, this failure could lead to loss of control of the sailplane.

Type: Rule
Date: 2005-10-05
Agency: Federal Aviation Administration, Department of Transportation
The FAA is adopting a new airworthiness directive (AD) for all Boeing Model 727 airplanes. This AD requires a one-time inspection of the lower lobe frames of body section 43 to find open holes between stringers 17L and 17R and to record their location; repetitive high frequency eddy current (HFEC) inspections for cracks of all open holes; and related investigative and corrective actions if necessary. This AD also includes an optional terminating action of installing rivets in all open tooling holes and all unused lining holes, which would terminate the repetitive open-hole HFEC inspections once a hole is plugged with a rivet. This AD results from reports of cracks at open tooling holes in the lower lobe frames of body section 43. We are issuing this AD to detect and correct cracks in the frames, which could result in cracks in the skin panels and rapid decompression of the airplane.
Airworthiness Directives; Boeing Model 747-100, -200B, -200F, -200C, -100B, -300, -100B SUD, -400, -400D, and -400F Series Airplanes; and Model 747SR Series Airplanes
Document Number: 05-19876
Type: Rule
Date: 2005-10-04
Agency: Federal Aviation Administration, Department of Transportation
The FAA is superseding two existing airworthiness directives (AD), which apply to certain Boeing transport category airplanes. One AD currently requires doing certain inspections to detect cracks and corrosion around the lower bearing of the actuator attach fittings of the inboard and outboard flaps; repairing if necessary; and either overhauling the fittings or replacing them, which ends certain repetitive inspections. The other AD currently requires certain other inspections to detect discrepancies of the actuator attach fittings of the flaps, and follow-on and corrective actions if necessary, which ends the repetitive inspections of the first AD. For certain airplanes, this AD requires new inspections for discrepancies of the actuator attach fittings of the flaps, and follow-on and corrective actions if necessary, which ends the repetitive inspections of both existing ADs. For all airplanes, this AD requires repetitive overhaul/replacements of the actuator attach fittings of both the inboard and outboard flaps. This AD results from reports of cracks of the actuator attach fittings of the trailing edge flaps. We are issuing this AD to prevent cracking and other damage of the actuator attach fittings of the trailing edge flaps, which could result in abnormal operation or retraction of a trailing edge flap, and possible loss of controllability of the airplane.
Airworthiness Directives; Sicma Aero Seat (Formerly Farner); Cabin Attendant Seat Series 150 Type FN and Series 151 Type WN
