(b) Who must comply with this AD? Anyone who wishes to operate any
airplane that incorporates one of the affected Honeywell automatic flight
control systems must comply with this AD.
(c) What problem does this AD address? The actions specified by this AD
are intended to prevent an undesirable autotrim command that the autopilot
cannot detect in the required time. The airplane could then deviate from the
selected altitude or the autopilot could disconnect without warning, which
could result in heavy loads at the control column. Such loads in the pitch axis
could result in loss of control of the airplane.
(d) What must I do to address this problem? To address this problem, you
must do the following actions, unless already done:
|
Action |
Compliance time |
Procedures |
|
(1) Inspect the KC 225 automatic flight control system
(AFCS) (Part Number 065-00183-0101, -0201, -0301, -0401, -0501, -0601, -2501,
-2601, -2701, -2801, -2901, or -3001) to determine the currently installed
computer modifications (Mods). These modifications are indicated on the AFCS
serial number tag. |
Within the next 10 hours time-in-service (TIS) after June
15, 2001 (the effective date of this AD). |
Do this following the Honeywell Installation Bulletin No.
472 Alert, Revision 1, dated January 2001. |
|
(2) If only Mods 1 and/or 2 are incorporated, accomplish the following: (i) Deactivate the KC 225 AFCS by pulling and banding the autopilot circuit breaker(s) to prevent operation of the KC 225 AFCS in flight; and. (ii) Fabricate a placard that
indicates the KC 225 AFCS is inoperative, and install this placard on the
instrument panel within the pilot's clear view. The placard should use
letters of at least 0.10-inch in height and contain the following words:
"KC 225 AFCS INOPERATIVE.". |
Prior to further flight after the inspection required by
paragraph (d)(1) of this AD. |
Accomplish the deactivation in accordance with Honeywell
Installation Bulletin No. 472 Alert, Revision 1, dated January 2001. The
owner/operator holding at least a private pilot certificate as authorized by
section 43.7 of the Federal Aviation Regulations (14 CFR 43.7) may accomplish
the placard requirements of paragraph (d)(2)(ii) of this AD. Make an entry
into the aircraft records showing compliance with this portion of the AD in
accordance with section 43.9 of the Federal Aviation Regulations (14 CFR
43.9). |
|
(3) As an alternative method of compliance to paragraphs (d)(2)(i) and (d)(2)(ii) of this AD for the KC 225 AFCS with only Mods 1 and/or 2 installed, accomplish either of the following to return the KC 225 AFCS to operation. (i) Return the AFCS to the
Honeywell Service Center for modification to install Mod 1, 2, and 3 (or
higher) levels and then incorporate this AFCS on the airplane; or. |
At any time as terminating action for all other requirements
of this AD. |
Do this following the Honeywell Installation Bulletin No.
472 Alert, Revision 1, dated January 2001. |
|
(4) If no Mods are installed or at least Mods 1, 2, and 3
are installed, ensure that the aircraft records identify Mod status. No further
action is required by this AD. |
Prior to further flight after the inspection required by
paragraph (d)(1) of this AD. |
Do this following the Honeywell Installation Bulletin No.
472 Alert, Revision 1, dated January 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 ACO.
Note: This AD applies to each airplane with a Honeywell automatic flight
control computer 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. You should include in
the request 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 Clyde Erwin, Aerospace Engineer, FAA,
Wichita Aircraft Certification Office, 1801 Airport Road, Room 100, Wichita,
Kansas 67209; telephone: (316) 946-4149; facsimile: (329)946-4407.
(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 Secs. 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 Honeywell
Installation Bulletin No. 472 Alert, Revision 1, dated January 2001. The
Director of the Federal Register approved this incorporation by reference under
5 U.S.C. 552(a) and 1 CFR part 51. You can get copies from Honeywell, Business
& General Aviation, One Technology Center, 23500 W. 105th Street, Olathe,
