Airworthiness Directive Certification
It is common knowledge that good record keeping forms the backbone of airworthiness and operational control. However, it is not always appreciated that the accuracy and legibility of the details contained in any record is just as crucial to any given recording system as the record itself.
No doubt you have been the victim of trying to decipher poorly printed or written information, but when detail is omitted the process can become something of a nightmare for the victim.
From reports received it is quite clear that a great deal time, and energy is unnecessarily expended unravelling the details contained in some aircraft log books, particularly the recording of compliance with Airworthiness Directives.
The details that record compliance with an Airworthiness Directive are not complete unless there is an indication of what part of the AD has been complied with.
|. AD/AIRCON/9 Amdt 5, contains three compliance parts.|
|. AD/BEECH 65/57 Amdt 3, contains two compliance parts.|
When making endorsements and certifications on maintenance releases or log books, remember that:
|. These records form a permanent part of the aircraft's records until one year after an aircraft's operating life has ended or has been permanently removed from the aircraft register;|
|. the instructions contained in the maintenance release and log book must be followed;|
|. all entries should be made in a way that gives due consideration to others who may need the information; and|
|. if the details of compliance and/or maintenance carried out are contained in other documents, make a reference to those documents in your endorsements.|
|. the Certificate of Registration holder or Operator will not appreciate incurring the extra cost of re-establishing compliance with a requirement due to insufficient or misleading endorsements.|
It may be considered a pain, but this may be a convenient time to have another look at the instructions contained in the aircraft log book and maintenance release. In fact, spending some time boning-up on the applicable certification requirements, such as Schedule 6 of the CAR's or other approved system of certification may not be a waste of time.
