ARRIVAL OF PARTS

• To ensure swift delivery of Parts, Materials and Tooling a Custom’s Agent must be engaged who has contacts at the HIGHEST LEVELS”. Arranging a “Custom’s Carnet” is of utmost importance to overcome “heavy” Customs Duties.

• To ensure these deliveries are completed with the utmost promptness, cooperation with all levels of the Airport Authority is required.

INCIDENT SITE SCRAP

• All scrap had to be collected for documentation.

• To conform to “Customs” regulations all parts and raw materials movements had to be thoroughly documented and presented to the Authorities for approval so as not to incur large Customs duties. This procedure was also required for all scrap material.

JANUARY 23 2000REPAIR BEGINS

• The Boeing Team begins the repair by first stabilising and “jigging” the Aircraft to prevent fuselage movement during the removal of the lower sections of Sections41 and 42.

pth13:

A/C was “tied” to the tail jack and the jack was cabled to the ground. Jack point was “drilled” to allow fitment of a rod between the jack adaptor and the jack point.

AIRCRAFT REPAIR BEGINS

STORES PERSONNEL

• A team of Stores Personnel was required to acquit all the Parts demands and to administer a Parts store to ensure a “smooth” production flow is maintained.

• Boeing were ordering “hundreds” of parts daily from Seattle and expecting 2 days delivery at the site.

DOCUMENTING AND CERTIFICATION

• To lessen the impact of the “cost” of the repair to QANTAS a lot of rotable parts were supplied by QANTAS. The Insurance Company will only pay “Market Price” for these parts.

• A Team of LAME’s were needed to document and certify these parts as a lot of the Parts were delivered straight from the Vendor. This included all the Landing Gear assembly’s.
