2001-17-21: This amendment adopts a new airworthiness directive (AD), applicable to certain McDonnell Douglas Model 717 series airplanes, that requires repetitive inspections of the rod ends of the spoiler hold-down actuators for breakage along the intersection of the thread runout and the outer spherical surface of the lug; and replacement of any broken rod end of the spoiler hold-down actuators with a new rod end. This AD also requires replacement of the rod ends of the spoiler hold-down actuators with new rod ends, and reidentification of the spoiler hold-down actuators, which constitutes terminating action for the repetitive inspections. This action is necessary to prevent failure of the rod ends of the spoiler hold-down actuators due to fatigue, which could result in loss of the back-up protection of the spoiler float hold-down and unavailability of monitoring for an uncommanded spoiler movement. This action is intended to address the identified unsafe condition. \n\n\tThe incorporation by reference of Boeing Alert Service Bulletin 717-27A0010, dated August 15, 2000; Boeing Service Bulletin 717-27-0013, dated January 30, 2001; and Boeing Service Bulletin 717-27-0013, Revision 01, dated February 28, 2001; as listed in the regulations, is approved by the Director of the Federal Register as of October 1, 2001.

To prevent loss of reliable altitude information, accomplish the following: (a) Unless already accomplished, within 12 months after the effective date of this AD: (1) Modify altimeter by replacing balance arm assembly with an assembly identified by an M-1 stamped on the brass portion thereof available from Weston Instruments, Inc., Weston-Garwin Carruth Division in accordance with Weston Instrument, Inc., Weston-Garwin Carruth Division Service Bulletin 600-0002 or equivalent approved by the Chief, Engineering and Manufacturing Branch, Central Region, FAA or (2) Replace the altimeter with an altimeter known to be airworthy. (b) Until the altimeter is modified or replaced in accordance with paragraph (a) of this AD, for those aircraft equipped with only one operative unmodified Weston-Garwin Carruth Model 22-374 Series Altimeter, (1) on and after the effective date of this AD, flight is limited to those conditions in which flight is maintained with visual reference to the ground and when flight visibility is 3 miles or better, and (2) within 10 hours flight time after the effective date of this AD a placard must be installed on the instrument panel in plain view of the pilot which states "This aircraft is limited to operations in those conditions in which flight is maintained with visual reference to the found and when flight visibility is 3 miles or better." (c) On and after the effective date of this AD, for those aircraft equipped with unmodified Weston-Garwin Carruth Model 22-374 Series Altimeter(s) the pilot shall accomplish the following in order to determine if the altimeter(s) is operative: (1) Prior to the commencement of flight, check the altimeter reading(s) against the known field elevation at the appropriate altimeter setting(s). If a deviation of more than 100 feet is observed in the altimeter reading and the aircraft is equipped with only one altimeter, further flight is prohibited until the altimeter is replaced with an altimeter known to be airworthy. If such a deviation is observed in one altimeter on an aircraft equipped with two unmodified Weston-Garwin Carruth Model 22-374 Series Altimeters, flight may only be accomplished in accordance with paragraph (b) of this AD. (2) During flight, check the altimeter(s) for erroneous or erratic reading(s). If such reading(s) are observed and the aircraft is equipped with only one altimeter, flight may be continued in accordance with subdivision (1) of paragraph (b) of this AD to the next point of intended landing. Flight beyond that point may be conducted only in accordance with FAR 21.197 to a base where repairs can be accomplished. If such reading(s) are observed in only one altimeter on an aircraft equipped with two unmodified Weston-Garwin Carruth Model 22-374 Series Altimeters, and the other altimeter is operative, flight may only be accomplished in accordance with paragraph (b) in this AD. This amendment effective September 18, 1967. Revised October 27, 1967.

2005-13-14: The FAA is adopting a new airworthiness directive (AD) for all McDonnell Douglas Model MD-90-30 airplanes. This AD requires replacing existing dual anti-skid control manifolds (DACM) with new, improved or reworked and reidentified DACMs; inspecting the inlet filters and other components of the DACMs for damage; replacing any damaged DACM components with new or serviceable components; and flushing/cleaning the braking system prior to replacing the inlet filters. This AD is prompted by reports of multiple incidents of blown tires on landing while using maximum autobrake. We are issuing this AD to prevent metallic fibers from the first stage filter of the servo valves inside the DACM from becoming lodged in the first stage nozzle of the servo valve, which could lead to tire failure during high speed/high energy braking and possible subsequent runway departure.

2005-13-05: The FAA is adopting a new airworthiness directive (AD) for certain Boeing Model 747-400F series airplanes. This AD requires initial detailed and open-hole high frequency eddy current inspections for cracking of the web, upper chord, and upper chord strap of the upper deck floor beams, and repair of any cracking. This AD also requires a preventive modification of the upper deck floor beams, and repetitive inspections for cracking after \naccomplishing the modification. This AD is prompted by reports of fatigue cracking found on the upper deck floor beam to frame attachment points. We are issuing this AD to prevent fatigue cracks in the upper chord, upper chord strap, and the web of the upper deck floor beams and resultant failure of the floor beams. Failure of a floor beam could result in damage to critical flight control cables and wire bundles that pass through the floor beam, and consequent loss of controllability of the airplane. Failure of the floor beam also could resultin the failure of the adjacent fuselage frames and skin, and consequent rapid decompression of the airplane.
