B5. One Off Certification Authorisation
In unforeseen circumstances where an aircraft is grounded at a location other than the main base where no appropriate certifying staff are available, the Chief Engineer may issue a one-off certification authorisation to:
1. A company employee holding type qualifications for aircraft of similar technology, construction and systems or;
2. To a person with no less than 3 years of maintenance experience and holding a valid ICAO aircraft maintenance license rated for the aircraft type, provided there are no organisations at that location approved in accordance with Part-CAO that could perform the work.In the case of item 2 above, the Chief Engineer willretain evidence of the experience and license of the person authorised. Form ABCD/005 will be used for the issue and recording of One Off Certification authorisations.
The Chief Engineer will ensure that where the above is issued, any task that could impact flight safety is rechecked by Certifying Staff at the earliest practical opportunity.
B6. Limited Certification Authorisations (Flight Crew)
When providing support to Commercial Operators, the Chief Engineer may authorise under this Part-CAO approval, the Pilot in Command (PIC) to perform:
1. Repetitive AD tasks where the AD specifically states that the AD may be accomplished by the flight crew and / or;
2. Limited maintenance tasks where the aircraft is operated away from a supported location. This willbe limited to simple tasks performed on non-critical / flight safety related systems, not requiring removal of cowlings or complete panels and not requiring further investigation as to the cause of the defect. (As an example, this could include navigation (position) light filament changes or top off the air in the aircraft tyre).The qualification to be checked and retained relating to items 1 & 2 above is a copy of the relevant valid Flight Crew License. In all cases, practical training and assessment on a task by task basis is to be provided such that the Chief Engineer can be entirely satisfied that the task can be completed to the required standard.
Flight Crew qualification, training, assessment and authorisation will be recorded on Form ABCD/004.
Note that this provision applies to commercial operation only where normal pilot owner maintenance is not permitted. Such authorisations will be listed in Section A10 of this CAE.
