What happened
The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.
(-23) The aircraft and passengers were enroute from mci to mso. While ascending through flight level 370 for flight level 390, the pilot heard a loud squeal and buzzing noise coming from the crew entry door. After a few minutes it got louder so the PIC elected to declare an emergency and diverted from his heading and landed at gri. After landing at gri without incident, the pilot and a mechanic found the door seal had ruptured causing the pressure to escape around the door seal. The door seal was deferred on the MEL and the aircraft was flown to oma for repair. The crew and passengers were uninjured and the aircraft sustained no damage. This incident is closed.
