(b) Who must comply with this AD? Anyone who wishes to
operate an aircraft equipped with one of the affected CTL-92 transponder
control panels must comply with this AD.
(c) What problem does this AD address? The actions
specified by this AD are intended to prevent erroneous altitude interpretations,
which could result in reduced vertical separation or unsafe traffic alert and
collision avoidance system (TCAS) resolution advisories.
(d) What must I do to address this problem? To address
this problem, you must accomplish the following actions:
|
Action |
Compliance
time |
Procedures |
|
(1) Modify the altitude encoder inputs of the CTL-92
transponder control panels. |
Within the next 10 hours time-in- service (TIS)
after August 20, 2001 (the effective date of this AD). |
Modify in accordance with the Accomplishment
Instructions section of Rockwell Collins Service Bulletin 33 (CTL-92-34-33),
dated April 5, 2001. |
|
(2) Do not install, on any aircraft, an affected
CTL-92 transponder control panel that has not been modified as required by
paragraph (d)(1) of this AD. |
As of August 20, 2001 (the effective date of this
AD). |
Modify in accordance with the Accomplishment
Instructions section of Rockwell Collins Service Bulletin 33 (CTL-92-34-33),
dated April 5, 2001. |
(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, approves your alternative. Send your request through an FAA Principal
Maintenance Inspector, who may add comments and then send it to the Manager,
Wichita Aircraft Certification Office.
Note: This AD applies to
any aircraft with the equipment installed as identified in paragraph (a) of this
AD, regardless of whether the aircraft has been modified, altered, or repaired
in the area subject to the requirements of this AD. For aircraft 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? You can contact Roger A.
Souter, FAA, Wichita Aircraft Certification Office (ACO), 1801 Airport Road,

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
