Palm Springs

After takeoff from Palm Springs Airport, while on a positioning flight to Boise, the crew encountered technical problems with the undercarriage. Following a holding circuit, the crew decided to return to Palm Springs and to complete a gear up landing. Upon touchdown, the aircraft slid on its belly for few dozen metres before coming to rest. Both pilots evacuated safely and the aircraft was damaged beyond repair.

The pilot departed the airport mid-morning to fly to his home airport, 63 miles to the northwest. Weather conditions at the departureb airport were visual flight rules (VFR), the weather at the destination airport was not reported, and the weather conditions en-route were marginal VFR. The global positioning system (GPS) track for the flight indicated that the airplane departed from the airport and headed west along a highway corridor flying approximately 1,000 feet above ground level (agl) through a mountain pass. For the majority of the flight, the airplane maintained altitudes between 900 feet and 1,200 feet agl. Twenty-nine minutes after takeoff, the airplane’s GPS track turned southwest away from an area of concentrated precipitation and directly towards an isolated mountain peak that rose approximately 1,000 feet above the surrounding terrain. The pilot contacted the local air traffic control facility, reported his position and requested traffic advisories through the local airspace to his destination airport. About 6 minutes later, the pilot stated that he was having difficulty maintaining VFR and asked for an instrument flight rules (IFR)clearance. At the same time, the GPS track showed that the airplane came within 50 feet of the mountainous terrain. No further transmissions from the pilot were received. The final GPS position was recorded 1 minute later, at 500 feet agl and approximately half a mile from the crash site. The terrain rapidly ascended in this area and intersected the airplane's flight path over the remaining 1/2 mile. An airport located about 4 miles from the accident site and in an area of flat terrain 1,000 feet below the isolated mountain top, recorded weather at the time of the accident as few clouds at 900 feet agl, overcast clouds at 1,500 feet agl, and a variable ceiling between 1,200 and 1,800 feet agl, in drizzle. Weather radar images at the time of the accident depicted precipitation at the elevation and location of the accident site, indicating probable mountain obscuration.

The airplane departed under daytime visual meteorological conditions on a cross-country flight from an airport on the east side of a mountain range to a destination on the west side of the mountains. The airplane, which had been receiving flight following, then collided with upsloping mountainous terrain in a mountain pass while in controlled flight after encountering instrument meteorological conditions. The controller terminated radar services due to anticipation of losing radar coverage within the mountainous pass area, and notified the pilot to contact the next sector once through the pass while staying northwest of an interstate highway due to opposing traffic on the south side of the highway. The pilot later contacted the controller asking if he still needed to remain on a northwesterly heading. The controller replied that he never assigned a northwesterly heading. No further radio communications were received from the accident airplane. Radar data revealed that while proceeding on a northeasterly course, the airplane climbed to an altitude of 6,400 feet mean sea level (msl). A few minutes later, the radar data showed the airplane turning to an easterly heading and initiating a climb to an altitude of 6,900 feet msl. The airplane then started descending in a right turn from 6,900 feet to 5,800 feet msl prior to it being lost from radar contact about 0.65 miles southeast of the accident site. A weather observation station located at the departure airport reported a scattered cloud layer at 10,000 feet above ground level (agl). A weather observation system located about 29 miles southwest of the accident site reported a broken cloud layer at 4,000 feet agl. A pilot, who was flying west bound at 8,500 feet through the same pass around the time of the accident, reported overcast cloud coverage in the area of the accident site that extended west of the mountains. The pilot stated that the ceiling was around 4,000 feet msl and the tops of the clouds were 7,000 feet msl or higher throughout the area. Postaccident examination of the airframe and both engines revealed no anomalies that would have precluded normal operation.

The airplane overran the runway after landing on runway 7. The passenger stated that he felt that the approach was "fast" and that the pilot was "behind the power curve" because of high
minimum en route altitudes in the area and that they had to "hustle down" during the descent. The passenger indicated that the flight crossed the runway threshold "maybe a bit more" that 10 knots above Vref and touched down about 10 knots above Vref. He said it was not a stabilized approach. Landing distance calculations and other evidence suggest that the lift dump panels did not extend after landing; however, the investigation did not determine the reason(s) for the lack of lift dump. No evidence was found of any failures affecting the lift dump or braking systems. Evidence and interview statements reveal that the pilot flew an unstabilized approach to the runway and landed well above target speed. The high landing speed was result of the pilot's excessive airspeed on the approach and a tailwind component of about 8 knots. Although the pilot landed the airplane within the touchdown area, the airplane's speed upon touchdown was about 17 knots above the prescribed speed. The flight's unstabilized approach and excessive speed should have prompted the pilot to initiate a missed approach.

While departing on a local area aircraft checkout flight the aircraft stayed low and the pilot advised the tower that he had a fuel problem. The aircraft had been fueled with aviation grade 100LL twice the day before in preparation for a trip. The pilot attempted to return to the airport, but collided with power lines 1.5 miles north. Examination of the engines revealed severe detonation had occurred. A fuel sample was obtained from the aircraft and tested negative for jet fuel contamination. The aircraft had been modified by installation of higher horsepower engines and turbochargers with manual wastegates. During postaccident examination of the aircraft systems the manual wastegates were found partially closed; a position that can provide additional manifold pressure. The engines are restricted to a maximum of 29.5 inHg.

The non-instrument rated, non multi-engine rated pilot, whose medical had expired, lost control of the aircraft during an IFR flight in instrument meteorological conditions. The aircraft crashed and burned. The pilot was attempting to return and land after he reported a landing gear problem. It could not be determined what landing gear malfunction existed.

A Cessna 441 operated by the US Customs Services collided with terrain while on an authorized night tactical flight. The copilot did not meet the currency standards as required by USCS and was not qualified in the aircraft. The flight originated during the daylight hours and continued to astronomical twilight. The pilots did not dark adapt previous to the night conditions. Dark adaption was impeded by flight through various light conditions created by terrain and ambient light levels. With night vision impeded the pilot would not have been able to distinguish relief of the terrain. The acft collided with a small ridge that abruptly rose 300 feet. Both occupants were killed.

After takeoff from Palm Springs Airport, while in initial climb, the pilot reported an engine failure and was cleared to return for an emergency landing. While making a turn, the twin engine airplane lost height, struck trees and crashed in a wooded area, bursting into flames. Both occupants were slightly injured.

Shortly after takeoff from Palm Springs Airport, while climbing by night at an altitude of 9,700 feet, the airplane struck a mountain located in the San Gorgonio Wilderness of the San Bernardino Mountains, about 22 miles northwest of Palm Springs. Due to very poor weather conditions, rescuers were able to reach the crash site three days later only. The aircraft struck the ground at a speed of 325 knots and disintegrated on impact. All four occupants were killed.

En route from San Diego to Palm Springs, weather conditions deteriorated and the twin engine airplane entered a thunderstorm area with severe turbulences and strong winds. The right empennage assembly and the right outboard wing panel failed in flight, causing the airplane to enter an uncontrolled descent and to crash in flames near Palm Desert. The aircraft was destroyed and all six occupants were killed.
