2003-24-07: This amendment adopts a new airworthiness directive (AD) that applies to all The New Piper Aircraft, Inc. (Piper) Models PA-31, PA- 31-300, PA-31-325, PA-31-350, PA-31P, PA-31T, PA-31T1, PA-31T2, PA- 31T3, and PA-31P-350 airplanes. This AD requires you to install an inspection hole (or use for inspection the tooling hole in the rudder bottom rib), conduct a detailed visual inspection of the rudder torque tube and associated ribs for corrosion, and, if corrosion is found, replace or repair the rib/rudder torque tube assembly. This AD is the result of reports of rudder tube corrosion. The actions specified by this AD are intended to detect and correct corrosion in the rudder torque tube assembly and rudder rib, which could result in failure of the rudder torque tube. This failure could lead to loss of rudder control.
2003-24-08: This amendment supersedes an existing airworthiness directive (AD), applicable to all Boeing Model 737-100, -200, -200C, -300, -400, and -500 series airplanes, that currently requires repetitive inspections to find cracks, fractures, or corrosion of each carriage spindle of the left and right outboard mid-flaps; and corrective action, if necessary. That AD also provides for an optional action of overhaul or replacement of the carriage spindles. This amendment requires repetitive gap checks of the inboard and outboard carriage of the outboard mid-flaps to detect fractured carriage spindles; and corrective actions, if necessary. This amendment also reduces the interval for the existing inspections and revises the overhaul procedures. The actions specified in this AD are intended to detect and correct cracked, corroded, or fractured carriage spindles and to prevent severe flap asymmetry, which could result in reduced control or loss of controllability of the airplane. This actionis intended to address the identified unsafe condition. \n\nDATES: Effective December 4, 2003.\n\nThe incorporation by reference of Boeing Alert Service Bulletin 737-57A1277, Revision 1, dated November 25, 2003, as listed in the regulations, is approved by the Director of the Federal Register as of December 4, 2003.\n\n\tThe incorporation by reference of Boeing Alert Service Bulletin 737-57A1277, dated July 25, 2002, as listed in the regulations, was approved previously by the Director of the Federal Register as of November 15, 2002 (67 FR 66316, October 31, 2002).\n\n\tComments for inclusion in the Rules Docket must be received on or before January 30, 2004.
2003-24-04: This amendment adopts a new airworthiness directive (AD), applicable to certain Boeing Model 747-400 and -400F series airplanes. This action requires replacing the rudder feel, centering, and trim mechanism with a new or serviceable rudder feel, centering, and trim mechanism. This action is necessary to prevent degradation/loss of rudder feel and centering, which could result in increased pilot workload and could lead to loss of control of the airplane. This action is intended to address the identified unsafe condition.
2003-23-03: This amendment supersedes an existing airworthiness directive (AD), applicable to certain Boeing Model 737-100, -200, and -200C series airplanes, that currently requires repetitive inspections to detect discrepancies in the upper and lower skins of the fuselage lap joint, and repair if necessary. This amendment adds new inspections, reduces the repetitive inspection intervals for certain airplanes, and mandates a terminating modification. The actions specified by this AD are intended to detect and correct discrepancies in the upper and lower skins of the fuselage lap joint and circumferential joint, which could result in sudden fracture and failure of a lap joint or circumferential joint and rapid decompression of the airplane fuselage. This action is intended to address the identified unsafe condition. \n\nDATES: Effective December 23, 2003.\n\n\tThe incorporation by reference of Boeing Alert Service Bulletin 737-53A1224, Revision 1, dated March 14, 2002, as listed in the regulations, is approved by the Director of the Federal Register as of December 23, 2003.\n\n\tThe incorporation by reference of Boeing Alert Service Bulletin 737-53A1224, dated August 17, 2000, as listed in the regulations, was approved previously by the Director of the Federal Register as of September 11, 2000 (65 FR 51750, August 25, 2000).
2003-22-10: This amendment adopts a new airworthiness directive (AD) for the specified Eurocopter France model helicopters that requires operators to either temporarily or permanently secure the electrical bonding braid (bonding braid) that is installed on the left cyclic pitch control stick base within 10 hours time-in-service (TIS) and, if temporarily secured, installing a permanent attachment system for the bonding braid within 500 hours TIS or 12 months, whichever occurs first. This amendment is prompted by a report of a bonding braid twisting around the attachment nut installed on the bolt that connects the roll channel torque link to the left-hand cyclic pitch control stick. The actions specified by this AD are intended to prevent an unsecured bonding braid from restricting travel to the cyclic pitch control stick, and subsequent loss of control of the helicopter.
2003-22-08: This amendment adopts a new airworthiness directive (AD), applicable to certain McDonnell Douglas Model MD-11 and -11F airplanes, that requires a one-time inspection of the barrel nut holes of the upper spar caps and skin panel of the horizontal stabilizer for corrosion, and follow-on and corrective actions if necessary. This action is necessary to prevent such corrosion, which could result in structural damage and consequent reduced controllability of the airplane. This action is intended to address the identified unsafe condition.
2003-22-07: The FAA is superseding Airworthiness Directive (AD) 97-20-14, which applies to all Mitsubishi Heavy Industries, Ltd. (Mitsubishi) MU-2B series airplanes. AD 97-20-14 currently requires incorporating information into the Limitations Section of the Airplane Flight Manual (AFM) that requires pilot training before flight into known or forecast icing conditions after a certain date. AD 97-20-14 resulted from the Federal Aviation Administration's analysis that the training level of the pilots-in-command (PIC) of the MU-2B series airplanes made it difficult for pilots to recognize adverse operating conditions and operate safely while flying in icing conditions. Since issuance of AD 97-20-14, a new training video has been developed that includes information that is critical to safety of the MU-2B series airplanes. This AD requires you to update the AFM information to require this new video as the mandatory pilot training. We are issuing this AD to decrease the chance of icing-relatedincidents or accidents of the MU-2B series airplanes due to pilot error.
2003-19-51: This document publishes in the Federal Register an amendment adopting airworthiness directive (AD) 2003-19-51 that was sent previously to all known U.S. owners and operators of certain Bombardier Model CL-600-2C10 (Regional Jet Series 700 & 701) and CL-600-2D24 (Regional Jet Series 900) series airplanes by individual notices. This AD requires repetitive detailed inspections for cracking or deformation, or pulled or missing fasteners, on the lower panel of the left- and right-hand main landing gear (MLG) doors, as applicable, and corrective actions if necessary. The actions specified by this AD are intended to prevent failure of the lower panel of the MLG door, the lower panel's departure from the airplane, and consequent damage to airplane structure, which could adversely affect the airplane's continued safe flight and landing. This action is intended to address the identified unsafe condition.
2003-16-19: This amendment adopts a new airworthiness directive (AD) that is applicable to all Learjet Model 45 airplanes. This action requires replacement of the horizontal stabilizer actuator assembly (HSAA) with a new HSAA. This action is necessary to prevent structural failure of the HSAA, which could result in possible loss of control of the airplane. This action is intended to address the identified unsafe condition.
2003-14-51: This document publishes in the Federal Register an amendment adopting Airworthiness Directive (AD) 2003-14-51, which was sent previously to all known U.S. owners and operators of the specified MD Helicopters, Inc. (MDHI) helicopters by individual letters. This AD requires checking and inspecting each main rotor blade retention bolt (bolt) and replacing the bolt with an airworthy bolt if necessary. The actions specified by this AD are intended to prevent failure of a bolt, loss of main rotor blade, and subsequent loss of control of the helicopter.
