|AWB 57-016 Issue 1(external link)||This AWB is applicable to Cessna 402C aircraft embodied with HDH Engineering Order EO 006-035 “Wing Main Spar Strap Modification”.
The purpose of this AWB is to advise operators and maintainers of the potential for deviation from approved design data in the installation of the Wing Main Spar Strap Modification.
It has come to CASA’s attention that Cessna 402C aircraft modified per HDH EO 006-035 may have components that have not been manufactured and installed strictly in accordance with the engineering drawings approved as part of this Engineering Order.
At this stage, two aircraft have been identified as potentially non-conforming with the drawings. This is being further investigated. The main discrepancy is pictured in photograph 1 on page 3, which shows the engine beam/spar strap reinforcement components that do not match the approved configuration per HDH EO 006-035. CASA recommends that operators, through their maintenance organisation, review the modification records and physical configuration of their aircraft.

This AWB provides information for accomplishing capacity tests to determine serviceability of lead acid batteries. Failures of batteries can result in costly AOG situations and catastrophic inflight emergencies.FAA AC 23.1309-1E states failure of electrical power is a catastrophic failure condition if primary flight instruments require electrical power. Batteries that have been discharged to the point where their cranking power has been diminished must NOT be jumped with another power source. The discharged battery may not be airworthy because it does not have the necessary capacity required to operate the aircraft avionics and electrical system in the event of generator failure.

Note: The assessment and inspection of harnesses is carried out in an environment involving personnel authorised for the task. The decision as to serviceability ultimately rests with these authorised personnel in combination with suitable guidance/criteria. Where no explicit criteria are given in maintenance instructions, the situation should be dealt with following appropriate best practice, including that presented in this Safety Notice. Whilst several manufacturers provide some guidance to support the safety harness maintenance tasks, this is generally only applicable to their products. This Safety Notice provides generic advice regarding safety harness inspection and maintenance practice for GA aircraft, identifying points to consider when establishing the ongoing integrity of the aircraft lap and shoulder harnesses.
