Practical Test Standards for the Aviation Mechanic; including General (FAA-S-8081-26), Airframe (FAA-S-8081-27), and Powerplant (FAA-S-8081-28), including Changes 1, 2, and 3.

Practical Test Standards are a guide for students, instructors, and FAA-designated examiners to know what is expected of pilots in a checkride.

Every PTS is written by the FAA and details the type and levels of skill and knowledge that must be demonstrated before an examiner can issue a certificate or rating to an applicant, and describes background study and reference materials.
