N588ET

HISTORY OF FLIGHTOn August 25, 2012, about 2145 Pacific daylight time, a Piper PA-32-301T Saratoga, N588ET, impacted trees shortly after departing from Lake Tahoe Airport, South Lake Tahoe, California. The right-seated pilot was operating the airplane under the provisions of Title 14 Code of Federal Regulations Part 91. The five occupants, which included the right and left-seated private pilots, were fatally injured; the airplane was destroyed. The personal cross-country flight was originating from Lake Tahoe Airport, with a planned destination of Fresno, California. Nighttime visual meteorological conditions prevailed, and no flight plan had been filed.

The occupants had departed Fresno earlier that day and landed at Lake Tahoe Airport. After touchdown, a pilot was in communication with two fixed base operator (FBO) attendants and received directions of where to taxi the airplane. While taxiing to the ramp, the airplane's engine shutdown and it took numerous attempts for the pilots to restart it. Upon parking, the pilots reported to the attendants that the airplane's fuel/air mixture was difficult to establish at such a high density altitude and that if one operates the engine too lean its temperature will exceed normal operation parameters. The pilots indicated that this was their first time of going to the Tahoe airport and he was under the impression that for the accident flight the left-seated pilot was the flying-pilot.

Following dinner, the occupants returned to the airport with the intention of flying back to Fresno, where the airplane was based. One of pilots made a radio transmission on the Common Traffic Advisory Frequency (UNICOM) stating that they were departing runway 36 and making a "straight out over the lake departure and then a crosswind departure to the left." This was the last radio call transmitted.

A review of the recorded security camera footage at the airport revealed that the airplane could be seen in the nighttime conditions by a blinking light. The airplane appeared to depart from runway 36 and near the end of the runway began an ascent. The light appeared to level off and then a flash of light occurs in the area of the accident site.

Numerous witnesses reported hearing the airplane depart and noticed that the engine noise sounded labored, as if it was not producing full power. A Civil Air Patrol Squadron Building was located at the airport where several cadets heard the departure and accident. A few cadets heard three "chirps," that sounded if the tires were touching back on the runway surface after becoming airborne. One cadet stated that one of the pilots showed signs of intoxication and noted that they forgot to turn the beacon on before startup and after takeoff. He observed the airplane become airborne far down the runway and appearing to be having engine problems. The airplane was only in the air about three seconds before descending and crashing into terrain. PERSONNEL INFORMATIONRight-seated Pilot

A review of the airmen records maintained by the Federal Aviation Administration (FAA) disclosed that the right-seated pilot, age 43, was issued a private pilot certificate with a rating for single-engine land airplanes in October 2007. His most recent third-class medical certificate was issued without limitation on June 20, 2012.

The pilot's personal flight logbooks were not recovered. According to his last application for a medical certificate, he reported a total flight time of 600 hours, 40 of which he accumulated in the 6 months prior to the medical examination. On his application form, the pilot reported that he had previously been convicted of a traffic violation consisting of a Driving Under the Influence (DUI) offense in 1994; he did not note any other convictions or violations.

The right-seated pilot owned the airplane, with the bill of sale showing a purchase date of December 2011. An acquaintance of the pilot stated that he sold him fuel about 1800 on the day of the accident in Fresno. The pilot indicated that he was going to fly to Tahoe for dinner. He recalled a recent conversation he had with the pilot when he advised him to lean the airplane's engine while operating on the ground while at high-elevation airports. He speculated that the pilot may have followed his advice, but then failed to enrich the mixture prior to departure.

Second Pilot

According to the FAA airmen records, the left-seated pilot, age 60, held a private pilot certificate with an airplane rating for single-engine land. His most recent third-class medical certificate was issued March 28, 2011 with the restriction that he must wear corrective lenses.

The left-seated pilot's personal flight records were not recovered. On his last application for a medical certificate, he reported a total flight time of 1,025 hours, of which 37 hours were accumulated in the last six months.

Passenger information

The passengers included the pilots' spouses and the right-seated pilots' six-year old daughter. Neither of the spouses were certificated pilots. AIRCRAFT INFORMATIONThe Piper PA-32-301T, serial number (s/n) 32-8024044, was manufactured in 1980. A review of the logbooks revealed that the most recent annual inspection of the airframe and engine was performed on September 14, 2011 at a total time of 3,380.76 hours,

The powerplant, a Lycoming Engines TIO-540-S1AD, s/n L5741-61A, was last overhauled in November 2007, equating to 212.76 operational hours before the last annual inspection. The maintenance records listed the last maintenance as occurring on February 14, 2012, at which time the following items were replaced: the vacuum pump, oil filter, co-pilot seat linkage rod, and battery. The propeller, installed in November 2007 under a supplemental type certificate (STC), was a MT-Propeller MTV-9-B (s/n 070165) composite 3-bladed propeller.

A review of the airplane's history revealed that it had been involved in an accident (MIA05LA070) in April 2006 causing substantial damage to the aircraft. The probable cause was determined to be a result of the pilot losing directional control during a crosswind landing.

According to the Lycoming Engines Illustrated Parts Catalog (IPC) PC 315-5, Section 2, page 2-5, the fuel pump installed on the engine was incorrect. The fuel pump listed for this engine model was RG-9570-P and a review of the engine logbook indicated that an RG9080J6A (s/n D-2570) had been installed at the overhaul dated October 17, 1991. The approval basis for the installation of this fuel pump was not documented in the record and could therefore not be determined. Additionally, there was no record indicating when the originally installed fuel pump was removed and the current one was installed.

Weight and Balance

Weight and balance computations were made for the accident takeoff and based on the airplane's empty weight, total moment, and center of gravity that were obtained from the maintenance records. The takeoff condition was calculated for a full fuel tank condition based on the FBO personnel statements and fuel receipts showing the addition of 32.3 gallons, which topped off the tanks with full fuel (total fuel capacity was 107 gallons, of which 5 gallons was unusable). The occupant weights and seating positions were obtained from the Department of Coroner, Sacramento, California and based on their self-reported driver's license weights; the child's weight was estimated. The detailed computations are appended to this report.

For the takeoff condition, the gross weight was about 3,557 pounds and the center of gravity was 91.78-inches. The maximum authorized gross takeoff weight was 3,600 pounds with the center of gravity range at that weight between 90 and 95 inches forward and aft, respectively.

Review of the Piper Aircraft Corporation Pilot's Operating Handbook (POH) for the airplane disclosed that with the flaps in the retracted position, at the maximum gross weight, the takeoff distance required over a 50-foot obstacle at maximum effort was just less than 3,000 feet. METEOROLOGICAL INFORMATIONA routine aviation weather report (METAR) generated by an Automated Surface Observation System (ASOS) at the airport, indicated that about 10 minutes after the accident the conditions were as follows: wind was from 200 degrees at 3 knots; temperature 16-degrees Celsius; dew point 3-degrees Celsius; sky clear; and altimeter 30.08 inHg. These conditions equate to a density altitude of 7,751 feet.

According to the U.S. Naval Observatory, on the night of the accident, the time of sunset was 1940. At the time of the accident, the moon was waxing gibbous with 64-percent of the visible disk illuminated -1.61 degrees below the horizon on an azimuth of 285 degrees.
