Piper PA-31-350 Navajo Chieftain

The twin engine aircraft was completing a charter flight from San Juan to Córdoba with seven passengers and two pilots on board. On approach to Córdoba-Ambrosio Taravella Airport by night, the crew encountered limited visibility due to poor weather conditions. The aircraft descended below the glide and collided with the inner marker antenna located about 700 metres short of runway 18 and crashed. Both pilots and four passengers were killed while three other passengers were seriously injured. Among those killed were the Argentinian racer Nicolas Vuyovich and Gustavo Ramonda, Director of the Toyota Corolla Racing Team who just won a race at the San Juan's autodrome.

The aircraft was on a scheduled cargo flight from Nanaimo, British Columbia, to the civilian terminal on the south side of the military airbase at Comox, British Columbia. The crew members established communication with the Comox tower when they were at about 2000 feet over Hornby Island, 12 nautical miles southeast of Comox, and requested a practice back course/localizer approach to Runway 30, circling for landing on Runway 18. The request was approved and the aircraft continued inbound. When the aircraft was about two miles from the threshold of Runway 30, the crew declared an emergency for an engine fire in the right engine. The tower alerted the airport response teams and requested standard data from the crew concerning the number of people and amount of fuel on board. Less than 30 seconds after the crew first reported the emergency, the aircraft was engulfed in flames. Shortly thereafter, at 0741 Pacific daylight time, the aircraft rolled inverted and struck the ground in a steep, nose-down, left-wing-low attitude. The aircraft broke apart and burned. Both crew members were fatally injured.

The aircraft was completing a flight from Charallave to Punto Fijo with seven passengers and one pilot on board. En route between Coro and Punto Fijo, while descending to Punto Fijo-Josefa Camejo Airport, the pilot encountered technical problems and elected to make an emergency on a motorway. Upon landing, the aircraft went out of control and came to rest upside down. All occupants escaped injured and the aircraft was destroyed.

The pilot was conducting a cargo flight in night instrument meteorological conditions, and was cleared for the ILS Runway 6L approach. The pilot reported that he was established on the localizer, and the control tower stated that the touchdown and mid-point "RVR" was 1,800 feet, and the roll-out "RVR" was 1,600 feet. The pilot also was instructed, and acknowledged, to make a right turn off the runway, after landing. There were no further communications from the airplane. The airplane's last radar target was observed at an altitude of 1,200 feet msl, and a ground speed of 130 knots. The airplane impacted trees, and came to rest inverted on airport property, on a bearing of 053 degrees, and a distance of 1/2 mile to the runway. Examination of the airplane did not reveal any pre-impact mechanical failures. A weather observation taken at the airport about the time of the accident included, winds from 140 degrees at 9 knots, 1/8 mile visibility, runway 06L visual range variable between 1,800, and 2,000 feet in fog, vertical visibility 100 feet, and a temperature and dew point 54 degrees F. The airport elevation was 1,009 feet msl. Review of the approach diagram for the ILS Runway 6L approach revealed a decision height of 1,198 feet msl, and an approach minimum of 1,800 feet runway visual range (RVR), or 1/2 mile visibility. The pilot had accumulated about 3,800 hours of total flight experience, which included about 350 hours in the same make and model as the accident airplane, and 250 total hours logged in instrument meteorological conditions.

The twin-engine airplane collided with a residential structure and terrain following a loss of control after the pilot experienced difficulties maintaining course during an Instrument Landing System (ILS) approach while on instrument meteorological conditions. The impact occurred approximately 3.7 miles short of the approach end of the runway. Radar data depicted that after the 8,700-hour commercial pilot was vectored to the ILS Runway 3 approach, the airplane remained left throughout the approach before turning right of the localizer approximately 2 miles before the final approach fix (FAF). Radar then showed the aircraft turn to the left of course line. When the aircraft was abeam the FAF, it was approximately 1 mile left of the course line. As the aircraft closed to approximately 1.5 miles from the runway threshold, the aircraft had veered about 1.3 miles left of the course line (at which time air traffic control instructed the pilot to turn left to a heading of 270 degrees). The aircraft continued to turn left through the assigned heading and appeared to be heading back to the ILS course line. According to the radar, another aircraft was inbound on the ILS course line and Air Traffic Control Tower (ATCT) instructed the pilot to turn left immediately. Thereafter, the aircraft went below radar coverage. A witness, located approximately 1.25 miles northwest of the accident site, reported that he heard a very loud noise, and then observed an airplane flying toward a building, approximately 60 feet in height. The airplane was observed to have pitched-up approximately 45 - 90 degrees just before the building and disappeared into the clouds. A second witness located approximately 1 mile northwest of the accident site reported that he heard a low flying aircraft, and then observed a white twin engine airplane banking left out of the clouds. The airplane leveled out, and flew into the clouds again a few seconds later. The witness stated that the airplane was at an altitude of 100- 200 feet above the ground. A third witness located adjacent to the accident site reported that they heard the sound of a low flying airplane in the distance. As the sound became louder and louder, they looked up and observed the airplane in a near vertical attitude as it impacted trees and the side of an apartment complex. Examination of the airplane did not reveal any preimpact mechanical anomalies. A weather observation taken approximately 15 minutes after the accident included a visibility 4 status miles, light drizzle and mist, and an overcast ceiling at 400 feet.

Before the start of the trip, the pilot was reportedly given $500.00 cash by the operator to purchase fuel. The pilot stated that the first leg of the flight from KFLL to MYEF departed with the main fuel tanks full and approximately 10 gallons in each of the auxiliary fuel tanks. There were no deviations en-route, and the uneventful flight lasted a reported 1 hour 40 minutes. After landing in Exuma International Airport, the main fuel tanks contained slightly more than 1/2 fuel capacity. Ten gallons of fuel were added to each of the two auxiliary fuel tanks at MYEF, no additional fuel was purchased. The flight departed for KFLL, and during the climb to 10,000 feet, he leaned the fuel/air mixture. During the cruise portion of the flight, the fuel in the auxiliary fuel tanks was consumed then he switched to the main fuel tanks to supply fuel to the engines. The flight crossed the DEKAL intersection at 4,000 feet, which is about 31 nautical miles southeast of KFLL, continued, and the right engine manifold pressure decreased, the cylinder head temperature reached red line indication, and the engine sputtered. He declared an emergency with air traffic control and the controller provided vectors to KFLL which he verbally acknowledged but did not comply with. While operating single engine, with the engine operating at full power, he reported no discrepancies with the left engine. He reported he could reach KFLL but was concerned about flying over a populated area at a low altitude, and was losing altitude. Contrary to the statement made by the pilot that he was not able to maintain altitude while flying single-engine, the airplane was capable of a rate of climb greater than 170 feet-per-minute if flown properly. He elected to ditch the airplane in the Atlantic Ocean; the airplane was not recovered. The operator was asked repeatedly by NTSB for historical fuel receipts and flight hours for N61518 but did not comply. NTSB review of fuel consumption calculations performed by the Federal Aviation Administration (FAA) Inspector-In-Charge revealed the aircraft would have experienced fuel exhaustion at the approximate location and time when the pilot declared an emergency with ATC following failure of the right engine. The NTSB did not receive the NTSB requested detailed, signed, dated statement from the pilot.

The airplane, which was not operating on a flight plan, was proceeding in clear skies to an airport where the passenger was joining his wife. After crossing a lake near the destination, the airplane flew over rising terrain, along a saddleback, until it struck a stand of old-growth trees that jutted above new-growth trees. During the last 48 seconds of radar coverage, the airplane climbed 600 feet with no erratic course deviations. From the accident location, the airport would have been about 5 nautical miles off the airplane's right wing. The pilot had 32,000 hours of flight experience. The passenger was under investigation for fraud, and attempted to obtain life insurance prior to the flight. The passenger had also loaned money to the pilot, and was receiving "flight services" in lieu of cash payment when the pilot failed to pay back the loan. A .380 caliber pistol magazine was found at the accident site with two rounds of ammunition missing; however, no weapon was located at the site, and no weapon of that caliber was known to be associated with either the pilot or the passenger. Premature ventricular complexes (PVCs) were found on electrocardiograms performed in conjunction with the pilot's airman medical certificate applications in 2002 and 2004. The pilot's autopsy report indicated "severe calcific... coronary disease, with 90 percent narrowing of the left anterior descending coronary artery and 75 percent narrowing of the right coronary artery." Cause of death, for both the pilot and passenger, was listed as "undetermined." The autopsy reports also noted that, "due to the inability to perform a complete autopsy...of either of the two aircraft occupants, it cannot be determined whether either the pilot or the passenger were alive or dead at the time of the crash." Post accident inspection of the airplane disclosed no evidence of any preimpact anomalies.

The Title 14, CFR Part 135 cargo flight departed for a destination airport about 20 miles downriver. Although weather at the departure airport was VFR, no reports of the actual weather along the route of flight were available. Unable to locate the destination airport due to deteriorating weather conditions, the pilot attempted to return to the departure airport following the river for ground reference. The airplane entered fog and whiteout weather conditions, and collided in-flight with the frozen surface of the river.

Crashed in unknown circumstances while on approach to Corozal-Las Brujas Airport. All three occupants were injured and the aircraft was destroyed.
