Built by a Grumman Owner, for Grumman Owners

I'm Jeff Johnson — owner of a 1975 AA-5B Tiger (N1595R) and Managing Director of Grumman-Parts.com, the largest online marketplace dedicated exclusively to Grumman AA and AG series aircraft parts.

I built this library because the information our fleet needs to stay safe and flying shouldn't be locked behind paywalls or scattered across dead forum links. Every manual, AD, service bulletin, and service letter on this site is free to download — no membership, no login.

I'm also the exclusive authorized distributor for the Trio Pro Pilot autopilot and an authorized uAvionix dealer. If you're planning an avionics or autopilot upgrade for your Grumman, I coordinate the entire project — mission review, panel configuration, GPS and EFIS compatibility, and installer coordination.
