2002-22-13: Flight management computers (FMC)

2002-22-13 Rockwell Collins, Inc.: Amendment 39-12939; Docket No. 2000-CE-13-AD. (a) What airplanes are affected by this AD? This AD affects Rockwell Collins flight management computers (FMC) specified in paragraph (a)(1) that are installed on, but not limited to, the aircraft specified in paragraph (a)(2). (1) Rockwell Collins flight management computers: The following presents the affected FMC models and part numbers: Affected FMC model No. Affected FMC Collins part No. FMC-4200 FMC-4200 FMC-4200 FMC-5000 FMC-6000 FMC-6000 FMC-6000 822-0783-002 822-0783-006 822-0783-010 822-0891-001 822-0868-004 822-0868-010 822-0868-021 (2) Affected airplanes: The following presents a list of aircraft (certificated in any category) that the affected Rockwell Collins FMC units are installed on (other airplanes could have the installation): Type certificate holder Affected airplanes Raytheon Bombardier Model Beechjet 400A and Model 400T (T-1A). Model CL-600-2B19 Regional Jet Series 100 and Model CL-600-2B16 (variant CL-604). (b) Who must comply with this AD? Anyone who wishes to operate an aircraft equipped with one of the affected FMCs must comply with this AD. (c) What problem does this AD address? The actions specified by this AD are intended to prevent the FMC from retaining original information when an edit is made to a procedure or flight plan. Such a condition could cause the pilot to fly the airplane out of the range of the correct altitude constraint. This condition could result in air traffic control or the pilot making flight decisions that put the airplane in unsafe flight conditions. (d) What actions must I accomplish to address this problem? To address this problem, you must accomplish the following: Actions Compliance (1) Remove the affected FMC unit specified in paragraph (a)(1) of this AD and install a modified or new FMC unit (as specified inparagraph (e) of this AD) in accordance with the applicable maintenance manual. (2) Do not install, on any aircraft, an affected FMC unit specified in paragraph (a)(1) of this AD that has not been modified to the replacement part number specified in paragraph (e) of this AD. Within the next 24 calendar months after December 20, 2002 (the effective date of this AD), unless already accomplished. As of December 20, 2002 (the effective date of this AD). Note 1: When selecting a replacement FMC part number, determine if the part number has been certified for installation on the particular aircraft through either the Type Certification or Supplemental Type Certification process. Also, determine whether additional avionics units must be upgraded at the same time to be compatible with the selected replacement FMC part number. (e) What are the acceptable replacement FMC part numbers? FMC affected part No. Acceptable replacement FMC part No. 822-0783-002 822-0783-006 822-0783-010 822-0891-001 822-0868-004 822-0868-010 822-0868-021 822-0783-011 or 822-0783-013 822-0783-011 or 822-0783-013 822-0783-011 or 822-0783-013 822-0891-005 or 822-0891-008 822-0868-029, 822-0868-030, 822-0868-031, or 822-0868-032 822-0868-029, 822-0868-030, 822-0868-031, or 822-0868-032 822-0868-029, 822-0868-030, 822-0868-031, or 822-0868-032 (f) Can I comply with this AD in any other way? You may use an alternative method of compliance or adjust the compliance time if: (1) Your alternative method of compliance provides an equivalent level of safety; and (2) The Manager, Wichita Aircraft Certification Office (ACO), approves your alternative. Submit your request through an FAA Principal Maintenance Inspector, who may add comments and then send it to the Manager, Wichita ACO. Note 2: This AD applies to each airplane identified in paragraph (a) of this AD, regardless of whether it has been modified, altered, or repaired in the area subjectto the requirements of this AD. For airplanes that have been modified, altered, or repaired so that the performance of the requirements of this AD is affected, the owner/ operator must request approval for an alternative method of compliance in accordance with paragraph (f) of this AD. The request should include an assessment of the effect of the modification, alteration, or repair on the unsafe condition addressed by this AD; and, if you have not eliminated the unsafe condition, specific actions you propose to address it. (g) Where can I get information about any already-approved alternative methods of compliance? Contact Roger A. Souter, FAA, Wichita Aircraft Certification Office (ACO), 1801 Airport Road, Rm 100, Wichita, Kansas 67209; telephone: (316) 946-4134; facsimile: (316) 946-4407. E-mail address: [email protected]. (h) What if I need to fly the airplane to another location to comply with this AD? The FAA can issue a special flight permit under sections 21.197 and 21.199 of the Federal Aviation Regulations (14 CFR 21.197 and 21.199) to operate your airplane to a location where you can accomplish the requirements of this AD. (i) When does this amendment become effective? This amendment becomes effective on December 20, 2002.
