What happened
The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.
(-23) At 4:30PM N2900S a Piper seneca departed Hyannis airport IFR going to new bedford. At 2600 feet the aircraft broke out of the clouds and leveled off at the assigned altitude of 3000 feet, the auto pilot was then engaged. The auto pilot failed to function properly and the pilot decided to return to Hyannis airport where griffin aviation would be able to troubleshoot the problem. The pilot received an amended clearance to Hyannis airport via radar vectors. The pilot also talked to ocean wings to inform them that he would be returning to Hyannis. The pilot received vectors for the ILS 15 approach into Hyannis. The pilot landed on runway 15. When applying the brakes the aircraft slid on the wet runway markings near the end of 33. The pilot rolled to a stop in the short grass of the end of runway 33 with no damage. Hyannis tower then instructed the pilot to hold his position on the grass and wait for airport operations to arrive. Airport operations arrived and determined there was no damage. Inspector statement: I interviewed the pilot on the day of the incident. The pilot stated to me that he broke out at about 2000', about a third of the way down the runway, too FAR down to get stopped in time. The weather at the time was 100' overcast with light rain and mist. I also spoke with the Hyannis tower controller who informed me that the pilot touched down with a slight tail wind and a bit fast. It appears that the pilot may have gotten lower than he liked and caught sight of the runway too late, causing him to land long.
