news:jVSKg.6851$SZ3.5261@dukeread04... That is true, but the engine did finally quit and it did not appear that there was any water ingestion to drown the engine. The video is not of high enough quality to know whether there was any water ingestion, especially since the engine doesn't shut down until the airplane has turned so that the engine is on the far side of the airplane from the camera. Once a jet is running, it takes shutting down the fuel supply to kill it, There are plenty of ways for a jet engine to stop running other than simply cutting off its fuel supply. Heck, you already mentioned one (water ingestion). And for that matter, there are ways for the fuel supply to be cut off other than actually exhausting the fuel supply. there was no one on the airplane. Since it was filmed, non-fatal and only minor injuries, it is possible that it was just left out of the report. I agree it's possible. But not nearly as likely as the engine shut down for a reason other than fuel exhaustion. Accident investigators are generally pretty thorough, to the point of including whether a pilot had filed a flight plan or not, even when there's almost never any relevance to that question. Clearly the PIC failed to calculate properly, to know his airport restrictions, but he sure did provide a great bit of video. Eh. The video was okay, IMHO. Obviously in a situation like this, it's unreasonable to expect a professional production value, but even simple things like having image stabilization (clearly not in use here) and deinterlacing the video for computer display (something that would have been done in post-processing) would have gone a long way toward making the video more watchable. I found it interesting enough to not feel I completely wasted the ten minutes it took to watch it, but I wouldn't call it "great". Pete |

... [...] That wasn't much of a tail wind. I'd guess either the runway was short or something else went wrong. It was wet so hydroplaning also could have been a problem. There was enough of a tailwind to add 500 feet to the landing distance, when the airplane was already going to require more distance to land than there was runway. Read the accident report. What "went wrong" is that the pilot tried to land at that airport. Pete |

It would be nice if, like the USNavy, a professional crew,
with the finest cameras filmed every TO and landing at every airport. These guys were just some airport bums with a camera and pickup truck. So the camera isn't stabilized, at least it was there. Had there been water ingestion, you would have seen steam. Also, the engine was well above the water when it was visible. There was no person on the airplane to shut it down. The pilot had come a long distance, northern Maine to Atlantic City. Water ingestion doesn't always kill a turbine engine, they run just fine in heavy rain. Even being submerged doesn't always kill the engine, it is still running after a 400 mph crash into the Pacific Ocean and comes up to menace Tom hanks in CASTAWAY and Hollywood certainly has the best technical advisors, cameras and they would not just make things up [humor].

I'll add some more, this video was given to the NTSB and not
sold to CNN. The camera was not the most modern, perhaps a law should be passed to require all video buffs to buy a new camera every month or so just so they'll have a camera that suits you. It was great that there was in fact video at all. It was a fun video to watch, to see a Citation seaplane. To see tyhe Boston Whaler boat. To find the NTSB report just Google "NTSB Bader Citation" without the quotes. NYC05LA085 On May 15, 2005, at 1548 eastern daylight time, a Danish-registered (OY-JET), Cessna Citation 525A, was substantially damaged during a runway overrun at Atlantic City Municipal Airport/Bader Field (AIY), Atlantic City, New Jersey. The certificated private pilot received minor injuries, and three passengers received no injuries. Visual meteorological conditions prevailed and an instrument flight rules (IFR) flight plan was filed for the flight which originated at the Burlington International Airport (BTV), Burlington, Vermont. The business flight was conducted under 14 CFR Part 91. The pilot reported to a Federal Aviation Administration (FAA) inspector, that he performed "one circle" around the airport, observed the windsock, and then performed a landing on runway 11. During the landing roll, approximately 2/3 down the runway, the pilot "lost the brakes," and was unable to stop on the remaining runway. The airplane then continued off the departure end of the runway and impacted the water. A review of recorded radar data and air traffic control (ATC) communications revealed the pilot contacted Atlantic City (ACY) Approach Control at 1538, and stated he was inbound to "alpha charlie yankee." The pilot was instructed to descend to an altitude of 2,000 feet, and fly heading 220 degrees. At 1540, ATC instructed the pilot to "proceed direct Bader, descend and maintain 1,500 feet. Expect visual approach." The pilot read back the instructions, stating, "thank you, direct Bader, descend to 1,500." At 1544, ATC informed the pilot that "the airport is 12 o'clock and 4 miles." The pilot responded that he had the airport in sight, and the controller then cleared the pilot for a "visual approach at Bader airport." Radar data indicated that the airplane was at an altitude of 800 feet, at 1545, continuing on a heading of 220 degrees. About 1 minute later, the airplane made a 360-degree right turn, and rolled out on it's previous heading of 220-degrees. At 1547:10, the airplane crossed abeam the departure end of runway 11, at AIY, at an altitude of 100 feet. The airplane then continued on a westerly (downwind) heading and climbed to an altitude of 300 feet. The airplane then initiated a right turn back toward runway 11, at an altitude of approximately 200 feet. During the turn, the airplane's groundspeed was approximately 180 knots. At 1548:42, the airplane was at an altitude of 200 feet, 1.24 nautical miles from the approach end of runway 11, with a groundspeed of 155 knots. Over the next 10 seconds, the airplane's altitude decreased to 0 feet, and the airspeed decreased to 140 knots. The last radar return was recorded approximately 1,000 feet beyond the approach end of runway 11, at an airspeed of 128 knots. A witness, who was an employee at AIY, was inside a trailer, located about 400 feet to the right of the midfield point of runway 11, at the time of the accident. The witness was in communication with a Cessna 182, on a downwind leg of the traffic pattern for runway 29, when he looked out the window and observed the accident airplane make a "low pass on runway 29 with a climbing right turn out." The witness went outside the trailer and observed the accident airplane touchdown "about halfway down" runway 11. The airplane appeared to slow as it approached the end of the runway; however, it did not stop, and subsequently impacted the water. The witness further reported that the pilot of the accident airplane did not communicate any intentions on the UNICOM frequency. Several other witnesses reported that as the airplane touched down, they thought braking was occurring, since smoke was coming from the airplane's tires. Examination of a video recording, which was taken by a witness at the airport, revealed the airplane touched down about 800-1,000 feet beyond the approach end of runway 11. The video also displayed the windsock at the airport, and according to the witness, it indicated a tailwind at 10-15 knots. The airplane was examined by an FAA inspector after the accident. According to the inspector, the brake system and emergency brake system were functionally checked, and no abnormalities were noted. The anti-skid system could not be tested, due to salt water damage. Examination of the emergency brake system revealed it had not been used, and the nitrogen bottle gauge indicated 1,800 psi. The flap selector was in the "ground" position, but the indicator was in the 15 degree position. The left throttle lever was observed in idle cut off, and the right throttle lever was bent to the right at the idle stop. Examination of the runway revealed tread marks beginning approximately two-thirds down the runway, and continuing off the departure end into the grass and dirt. The winds reported at Atlantic City International Airport (ACY), 9 miles to the northwest, at 1554, were from 280 degrees at 9 knots. A review of the FAA Airport/Facility Directory for the Northeast U.S., revealed the following notation listed in the Airport Remarks section of the Atlantic City/Bader Field Airport entry, "Arpt CLOSED to jet traffic." Additionally, runway 11 was a 2,948 foot-long, 100 foot-wide, asphalt runway. Additionally, the airport diagram for Bader Field, was observed attached to the pilot's control column after the accident. A notation, which read, "airport closed to jet aircraft" was observed on the diagram. According to the Cessna 525A Landing Distance Chart, an airplane with a landing weight of 11,400 pounds required 3,000 feet of landing distance, in a no wind situation. With a 10 knot tailwind, the airplane required 3,570 feet of landing distance.

There was enough of a tailwind to add 500 feet to the landing distance, when the airplane was already going to require more distance to land than there was runway. And most probably to shift the touch down point a couple of hundred feet down the runway, too. Don't ask me why I know this. My guess is that the same water which caused the short circuit by creeping into the electrics and launched the engine creeped further and cut the fuel pump. Just my guess, not better nor worse than other guesses. Stefan |

Jet engines run rather well with no electric power what-so-ever. Mechanical fuel pumps. A more likely situation would be that water entered the fuel tank vent system and jets don't like to run on water very well. Bob Moore |

The last radar return was recorded
approximately 1,000 feet beyond the approach end of runway 11, at an airspeed of 128 knots. I assume they mistyped, and meant ground speed? (the difference would be important) Jose -- The monkey turns the crank and thinks he's making the music. for Email, make the obvious change in the address. |

Watch it all. I know it's not right to say this, but... Somehow, the registration number is nearly perfect for the situation. The only thing better/worse might have been OY-VEY Peter |
