Airworthiness Directive · Amendment 39-13993 · Airbus Model A300 B4-600, B4-600R, and F4-600R Series Airplanes, and Model C4-605R Variant F Airplanes (Collectively Called A300-600); and Model A310 Series Airplanes; Equipped With Certain Honeywell Inertial Reference Units (IRU)
Airbus Model A300 B4-600, B4-600R, and F4-600R Series Airplanes, and Model C4-605R Variant F Airplanes (Collectively Called A300-600); and Model A310 Series Airplanes; Equipped With Certain Honeywell Inertial Reference Units (IRU)
This AD applies to Airbus airplanes, certificated in any category; as identified in Table 1 of this AD:
| Model— | Equipped with any honeywell inertial reference unit (IRU) having part number— | Excluding airplanes modified in accordance with— |
|---|---|---|
| A300 B4-600, B4-600R, and F4-600R series airplanes; and C4-605R Variant F airplanes (collectively called A300-600) | HG1050BD01, HG1050BD02, or HG1050BD05 | Airbus modification 12304 in production. |
| A310 series airplanes | HG1050BD01, HG1050BD02, or HG1050BD05 | Airbus modification 12304 in production. |
The FAA is adopting a new airworthiness directive (AD) for all Airbus Model A300 B4-600, B4-600R, and F4-600R series airplanes, and Model C4-605R Variant F airplanes (collectively called A300-600); and Model A310 series airplanes; equipped with certain Honeywell inertial reference units (IRUs). This AD requires revising the Limitations section of the airplane flight manual to prohibit the use of CAT 2 and CAT 3 automatic landing and rollout procedures at certain airports. This AD is prompted by a report that some magnetic deviation tables in the IRU database are obsolete and contain significant differences with the real magnetic deviations. We are issuing this AD to prevent an airplane from deviating from the runway centerline, and possibly departing the runway.
You are responsible for having the actions required by this AD performed within the compliance times specified, unless the actions have already been done.
Within 10 days after the effective date of this AD, revise the Limitations section of the Airbus A300-600 AFM; or the Airbus A310 AFM; as applicable; by inserting a copy of the applicable Airbus temporary revision (TR) listed in Table 2 of this AD into the applicable AFM.
Note 1: When Airbus includes these TRs in the general revisions of the AFM, the general revisions may be inserted in the AFM, provided the relevant information in the general revisions is identical to that in Airbus TRs 6.01.03/08 and 6.01.03/36.
| For model | Airbus temporary revision | AFM |
|---|---|---|
| A300-600 airplanes | 6.01.03/08, dated February 9, 2004 | A300-600 Flight Manual. |
| A310 series airplanes | 6.01.03/36, dated February 9, 2004 | A310 Flight Manual. |
After replacing the Honeywell IRUs with new or modified Honeywell IRUs in accordance with the requirements of AD 2003-20-01, amendment 39-13319 (68 FR 55814), the AFM revision required by paragraph (f) of this AD may be removed.
The aircraft, engines and makers this AD names, by the model designations in its text. A model listed here may still be outside the AD's serial ranges.
