These checks are done by taking selected measurements for comparison with the measurements taken at the
same points when the aircraft was prepared for delivery at the manufacturers.
Before the checks are done:
1
The aircraft must be empty of fuel.
2
The aircraft must be parked in a hangar for a minimum of one hour.
3
The aircraft must not be exposed to direct sunlight.

A record of the Aircraft Build Checks can be obtained from Pilatus Aircraft Ltd.
If the measurements taken are not in the limits given, the aircraft must not be operated, and Pilatus advised
before any further action is taken.
Pilatus will provide any assistance required on receipt of copies of the In-Service Check Form and
Comparison Table and a full report on the incident which made the check necessary. Details of structural
damage discovered during the subsequent investigation, should also be included.
