Summary of deficiency, proposed amendment and justification
Book IV Chapter 2 para 1.27 states; Where the removal of a component is required during the course of a rectification, the entry shall detail the component removed, the reason for removal and refer to the original defect, e.g. ‘No 1 hydraulic pump cover removed for access (or ‘RFA’) in accordance with (or ‘IAW’) (enter details), refer serial number of work (or ‘RSN’) 123456’.
While this process documents the removal of the component and the current state of the aircraft it does not enable the requirement for all trades persons to endorse all maintenance carried out (para 1.2, 1.3 and 1.6), neither does it record who carried out the supervision of the maintenance. We now have maintenance conducted on the aircraft and can’t identify who carried it out.
If the defect read, ‘No 1 hydraulic pump cover to be removed and installed to facilitate work at refer serial number of work (or ‘RSN’) 123456’.
A Sub US would be raised for the removal and one for the installation; thus meeting the requirements at paras 1.2, 1.3 and 1.6.
Or change 1.27 to read
‘1.27 Where the removal of a component is required during the course of a rectification, and the installation is to be carried out by a different trades persons, two defects are to be raised one for the removal and one for installation. The certification of the removal of the item cannot be conducted unless the installation defect is raised, as a CRS cannot be issued with a known defect endangering flight safety; thus meeting the requirements at paras 1.2, 1.3 and 1.6.
