Unresponsive Cessna 421 Pilot Crashes in Gulf of Mexico

Cessna 421 Crash

The flight path of the Cessna 421 shows the
airplane flying erratically before crashing in the
Gulf of Mexico.

Authorities have suspended the search for the body of the Cessna 421 pilot who crashed into the Gulf of Mexico Thursday afternoon after remaining unresponsive to air traffic control calls for several hours.

The Cessna 421 took off from Slidell, Louisiana, on Thursday morning and headed southeast over the Gulf, but drew concern from air traffic controllers around 9 a.m. when they lost contact with the pilot. As the aircraft circled erratically over the Gulf in the region near Eglin Air Force Base, Florida, controllers at the Jacksonville Air Traffic Control Center requested two F-15s flying in the area to assess the situation.

According to a report from the Associated Press, the Air Force pilots witnessed the aircraft, with iced-over windows, vacillating between 25,000 and 35,000 feet.

The airplane went down around noon approximately 120 miles west of Tampa, remaining intact and upright before beginning to sink into the 1,500-foot-deep water. Members of the Coast Guard who witnessed the accident from above saw no signs that the pilot was still alive after the crash-landing.

The airplane had flight planned for 27,000 feet and 215 knots along a Gulf of Mexico high-altitude route. The flight from Slidell, Louisiana, to Bradenton, Florida, was expected to last around three and a half hours.

A 65-year-old doctor from the New Orleans area has been identified as the pilot flying the 421, which is a pressurized piston twin with a service ceiling of around 30,000 feet and a regulatory ceiling of 28,000 feet. The aircraft is typically flown in the low flight levels.

While the cause of the crash is still unknown, comparisons to the 1999 crash that killed golfer Payne Stewart and five other occupants aboard a Learjet after the aircraft lost cabin pressure over the Gulf have already begun.

I am a 421C Owner Pilot and first, my condolences to the Pilots family. I'm so sorry to read we have lost another pilot, I just hate reading these reports. The mystery: To file and fly a 421C at 27,000' - FL 270 - means the plane would have to be very tight, as if it was not, the small amount of Preasurization available to all 421 drivers, would not give much of a breathable enviroment at that Flight Level. As the article mentions, most 421 pilots fly in the lower flight levels, mainly because most 421s do not pump up to the max differntial as they get older. I generally don't fly mine over 24,000' (FL 240) for that very reason, even then, I would be wearing an oxygen mask, just for safety, and always if single pilot over FL240.

Is the regulatory ceiling lower because of the relatively high age of the aircraft?

I was alerted to a failure to pressurize in a King Air by a packet of potato chips that burst going through 16,000' for a final FL210. IIRC the only warning is a yellow light on the annunciator panel. Always carry an unopened packet of potato chips with you, it may save your life. I've also flown the 421, max FL260.

To iused2fly,

The regulation is that above FL 280 aircraft and operators must me certified to RVSM standards which is reduced vertical separation minimum. It has nothing to do with the aging aircraft other than expense to re-equip an older piston twin to meet the requirement. The RVSM standards allow a continued 1,000 foot vertical separation above FL 280 to and including FL 410. Above that it goes back to the 2,000 foot separation minimum.

Excellent idea. My wife and I had the same experience with potato chips in our un-pressurized Piper Warrior at 10,000 ft, while climbing through haze on a cross country. It scared the heck out of both of us. While I'm checking engine instruments and aircraft integrity my wife suddenly said; "It's Ok, I can smell potato chips". It suddenly hit us both and we had a good laugh. But seriously, Sporty's may be missing a great marketing idea to sell a compact item which could hang inconspicuously on the bulkhead and be designed to explode at a pre-assigned altitude. It could be a life saver.
