- Great to get the airplane airborne again after so much work by the team.
This functional check flight was to reclear the airplane post maintenance. Between the brakes and the hydraulic system much of the flying focused on the gear. After the third gear retraction went much slower than expected we decided to cut out the multiple landing circuits that were planned. On descent there was an intermittent inner gear door light, which appeared to be related to airspeed. From the video though we could see that the gear never locked up.

Postflight:
Uplock found to be out of adjustment, which is likely why the gear was sagging. The lock was removed and sent to the manufacturer for assessment.
Talking to other Stewart Mustang operators, it sounds like many have lowered VLO from the published 130 MIAS. Many have found the gear has trouble retracting at this speed.
