Table 1 - Concurrent Requirements

For Aeroplanes Identified in Boeing CSB

Action

233A3205-24-01 dated
26 July 2001

Modify the generator drive and standby power module assembly in accordance with the Accomplishment Instructions of the CSB.

69-37319-21-02, Revision 1, dated 30 August 2001

Modify the air conditioning module assembly in accordance with the Accomplishment Instructions of the CSB.

Later revisions of the above SBs, approved by the United States Federal Aviation Administration (FAA) as an Alternate Method of Compliance (AMOC) to FAA AD 2006-10-17, are considered acceptable for compliance with the equivalent Requirements of this Directive.

Note 2: FAA AD 2006-10-17 Amdt 39-14601 refers.

Compliance:

For Requirement 1 - Within 36 months after the effective date of this Directive.

For Requirement 2 - Before further flight after the Requirement 1.b. inspection.

For Requirement 3 - Either concurrently with or before Requirement 1.

This Airworthiness Directive becomes effective on 3 August 2006.

Background:

This Directive requires replacing brackets that hold the P5 panel to the aeroplane structure, the standby compass bracket assembly, the generator drive and standby power module together with the air conditioning module. The Directive also requires, among other actions, inspecting for wire length and for damage of the connectors and the wire bundles, together with the accomplishment of any necessary corrective actions.

Actions specified by this Directive are designed to prevent wire bundles from contacting the overhead dripshield panel and modules in the P5 overhead panel, which could result in electrical arcing and shorting of the electrical connector and consequent loss of several critical systems essential for safe flight.
