(b) Who must comply with this AD? Anyone who wishes to operate any
airplane that uses one of the above referenced Rockwell Collins air data
computers must comply with this AD.
(c) What problem does this AD address? The actions specified by this AD
are intended to prevent an unwarranted display of the ADC flag when switching
static air sources. This could cause the flight crew to react to this incorrect
flight information and possibly result in an unsafe operating condition.
(d) What actions must I accomplish to address this problem? To address
this problem, you must accomplish the following:
|
Actions |
Compliance |
Procedures |
|
(1)
Perform the following, unless already accomplished: |
Within
the next 12 calendar months after August 23, 2002 (the effective date of this
AD). |
In accordance
with Rockwell Collins Service Bulletin No. 62, Revision No. 2,
ADC-85/85A/850C/850D/850E/850F-34-62), Revision No. 2, dated March 7, 2000,
or Service Bulletin No. 62, dated October 25, 1999, as applicable, the
applicable Collins Computer Component Maintenance Manual, and Collins
Avionics Standard Shop Practices Instruction Manual. |
|
(2) Do
not install on any airplane one of the affected ADCs unless the modification
and test required by paragraphs (d)(1)(ii) and (d)(1)(iii) of this AD are
accomplished |
As of
August 23, 2002 (the Service date of this AD). |
In
accordance with Rockwell Collins Service Bulletin No. 62, Revision No. 2,
ADC-85/85A/850C/850D/850E/850F-34-62, dated March 7, 2000, or Service
Bulletin No. 62, dated October 25, 1999, as applicable. |
Note 1: Rockwell Collins Operator Bulletin 99-7, dated August 1999,
contains information about an operational placard to install until
accomplishment of the actions of this AD. While not necessary to address the
unsafe condition in this AD, FAA highly recommends that you incorporate this
placard.
(e) 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 subject to 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 (e) 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.
(f) 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, Room 100, Wichita, Kansas 67209;
telephone: (316) 946-4134; facsimile: (316) 946-4407, E-mail:
Roger.Souter@faa.gov.
(g) 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.
(h) Are any service bulletins incorporated into this AD by reference?
Actions required by this AD must be done in accordance with Rockwell Collins
Service Bulletin No. 62, Revision No. 2, ADC-85/85A/850C/850D/850E/850F-34-62,
dated March 7, 2000, or Rockwell Collins Service Bulletin No. 62,
ADC-85/85A/850C/850F-34-62, dated October 25, 1999. The Director of the Federal
Register approved this incorporation by reference under 5 U.S.C. 552(a) and 1
