Which form is associated with documenting engine data and operating time?

• A. AFTO form 781H (health)
• B. AFTO form 781F (front)
• C. AFTO form 46
• D. AFTO form 781J (jet)

Answer: (D)

AFTO form 781J is used to document jet engine data and operating time. It is the jet-specific entry in the AFTO 781 series that records engine run hours, time since last overhaul or inspection, and related maintenance actions, creating a reliable log for scheduling maintenance and ensuring airworthiness. Other forms in the AFTO 781 family cover different aspects—such as general health information or the front-page summary—but they do not focus on accumulating and tracking engine operating hours like 781J does.
