Runway departure on landing.
PIC: ATP, Part 91.
JFK (J F Kennedy, New York NY).
Cessna Citation X.
Prelim report (no injuries).
On 04-03-08 at 20:14 EDT, a Cessna Citation X received substantial damage when the aircraft departed the right side of Runway 13L at JFK (J F Kennedy, New York NY) while on rollout. There were no injuries. Both pilots stated that the aircraft touched down within the first 1000 ft of the runway.
According to the copilot, who was flying the aircraft, it yawed to the right when he applied thrust reversers after touchdown. The right reverser arm, unlock and deploy light illuminated. The copilot took the reversers out of reverse, aligned the aircraft with the runway centerline and applied normal brakes. He noted that the brakes were spongy and that he informed the PIC that he had no brakes. The PIC deployed the emergency brakes and the aircraft slowed straight ahead, subsequently yawing to the right. Since the copilot was unable to maintain directional control, the aircraft went off the side of the runway.
Cessna downloaded the aircraft's engine indicating and crew alerting system (EICAS). The download revealed that an amber "HYD VOLUME LOW A" abnormal indication light had illuminated at 19:43, followed at 19:46 by an amber "HYD PUMP UNLOAD A" warning light. At 19:55, an amber "HYD PTU FAIL" warning light illuminated.
Both crewmembers stated that they did not report the malfunction to ATC. They added that the "HYD VOLUME LOW A" light came on when the flight was about 20 miles out from JFK. Asked if he had observed the additional amber indication lights, the PIC said he was aware of the messages but assumed they were the result of going through the checklist.
Collision with vehicle on landing.

DUT (Unalaska AK).
Grumman G21A Goose.
Prelim report (9 injuries).
A Grumman Goose amphibian was substantially damaged on the afternoon of 04-09-08 after striking a trailer van on a road adjacent to the approach end of Runway 30 at DUT (Unalaska AK).
Landing procedures for Rwy 30 are outlined in the Alaska Flight Information Supplement, which states, in part, "Stop light for vehicle traffic crossing Runway 30 threshold must be activated and deactivated for each aircraft operation over the threshold." It also says, "Stop light for vehicle traffic crossing Runway 30 threshold, key 122.6 7 times for on, 3 times for stop light and REIL off."
There are 2 remotely-controlled gates with warning lights on each side of the runway threshold. These are designed to block vehicle traffic while airplanes land on Rwy 30. The pilot reported that he activated the lights.
An interview with the truck driver revealed that he had seen the flashing red lights but that the gate was not down. He reported that he had been working at the airport for 4 months and that the gates had been broken the entire time. He also stated that the flashing lights activated occasionally when no landing traffic was present. He said that he waited for approximately 45 seconds and looked. Seeing no landing traffic, he started across.
The pilot reported seeing the stopped truck and watching to ensure it was not moving. He had configured the aircraft for landing but, as he approached the runway threshold, noticed that the truck had begun to move. The pilot applied full power and attempted a go-around.
A safety representative from the State of Alaska's DOT reported that the gates have been out of service for more than a year due to budgetary constraints and pending equipment upgrades.

T74 (Taylor TX).
Beech King Air 200.
Prelim report (1 killed).
On the morning of 04-11-08, following a local maintenance test flight from T74 (Taylor TX) for a replaced vertical speed indicator, the pilot of the King Air 200 taxied to the ramp. He reported to the mechanic that during the flight he had heard a loud, high-pitched screaming sound.
The mechanic wished to board the airplane with the engines at idle to troubleshoot the problem. However, when he opened the door, the pressure in the cabin had not dissipated and the door struck his head with significant force. The mechanic died from his injuries.
