Circumstances:
At the time of the accident, gusty winds were forecast for the surface to higher altitudes. The copilot was flying and configured the airplane about four miles out for landing on runway 24. The flightcrew received progressive wind information during the approach; the last report was wind at 310° and 25 knots. The approach speed was v ref + 10. According to the flightcrew, during the landing flare a wind gust occurred, and the airplane lifted in a nose down attitude. The gust stopped and then the airplane descended to the runway and landed hard. The examination of the airplane revealed the fuselage cracked near where the wings were attached and the aft fuselage was bent down about 7°. Two passengers were seriously injured.
Probable cause:
The aircraft encountered a sudden wind gust during landing flare, which resulted in a hard landing.

Circumstances:
The pilot stated that he was utilizing the autopilot and flight director to execute the ILS approach to runway 32. The autopilot was tracking the localizer while the pilot controlled the rate of descent along the glideslope with pitch command wheel on the autopilot, using the command bars as a steering reference in addition to the raw data glideslope needle on the hsi. All seemed normal, according to the pilot, until the aircraft struck trees about 450 feet above airport elevation two miles short of the runway and came to rest on the localizer centerline. A zero feet ceiling with an eighth mile visibility existed at the airport. During the investigations, it was determined that the 1000 a ifcs will not provide vertical steering commands as operated by the pilot, but is driven by the pitch wheel. This is not specifically stated in the poh. The pilot had flown extensively with the 800 series ifcs which will provide the expected steering commands. Extensive damage precluded a functional test of the raw data glideslope needle. Both occupants were slightly injured.
Probable cause:
Occurrence #1: in flight collision with terrain/water
Phase of operation: approach - faf/outer marker to threshold (IFR)
Findings
1. (c) proper glidepath - not maintained - pilot in command
2. (c) reason for occurrence undetermined
3. (f) flight/navigation instrument(s) - improper use of - pilot in command
4. (f) weather condition - below approach/landing minimums

Occurrence #2: fire

Circumstances:
The airplane crashed while attempting an approach to Tompkins County Airport, Ithaca, New York, an en route stop from schedule flight 141 from Utica to Washington DC. The flight crew had contacted Elmira approach control and had received instructions for an instrument landing system (ILS) approach to runway 32 at Tompkins County Airport. About 07:40 EST, the copilot declared an emergency stating that the airplane had a landing flap problem; he later stated that only one flap was down. He also stated that they were not able to maintain altitude and that the airplane was descending. Elmira approach lost radar contact with the airplane about 07:41 EST; the last radio transmission from the flight was recorded about 07:45 EST. The airplane crashed in a wooded area near three suburban residences. The pilot and copilot, the only persons aboard, were killed. There were no injuries to personnel on the ground. The airplane was destroyed by impact and post impact fire.
Probable cause:
The probable cause of the accident was excessive wear of the left flap motor/flexible drive spline and certification of the airplane with a flap system that did not meet the requirements of Civil Air Regulation 3.339. The worn spline caused a split flap condition of 34 that resulted in marginal flight control authority. Moderate low altitude turbulence and transient low level wind shear may have contributed to the upset and loss of control.
