AD NUMBER: 2018-03-15

PRODUCT: Pacific Aerospace Limited Model 750XL airplanes.

ACTION: Final Rule, request for comments.

SUMMARY: This AD results from mandatory continuing airworthiness information (MCAI) issued by the aviation authority of another country to identify and correct an unsafe condition on an aviation product.

The MCAI describes the unsafe condition as abrasion damage of components or wiring behind the instrument panel.

DATES: This AD is effective March 5, 2018. The Director of the Federal Register approved the incorporation by reference of a certain publication listed in the AD as of March 5, 2018. Comments on this AD must be received by March 30, 2018.

COST: The FAA estimates that this AD will affect 22 products of U.S. registry. It further estimate that it would take about 3 work-hours per product to comply with the basic requirements of this AD.

The average labor rate is $85 per work-hour. Required parts would cost about $90 per product. Based on these figures, the FAA estimates the cost of the AD on U.S. operators to be $7,590, or $345 per product. The extent of abrasion damage could vary from airplane to airplane.

The FAA has no way of knowing how many airplanes may have abrasion damage or the extent of that damage; and so has no way of determining an estimated cost for repair.
