N286CD

HISTORY OF FLIGHT

On February 6, 2005, about 1820 Pacific standard time, a Cirrus Design SR22 G2, N286CD, impacted mountainous terrain after encountering icing conditions near Norden, California. The owner/pilot was operating the airplane under the provisions of 14 CFR Part 91. The private pilot, the sole occupant, sustained fatal injuries; the airplane was destroyed. The personal cross-country flight departed Reno/Tahoe International Airport (RNO), Reno, Nevada, about 1750, en route to Oakland, California. Instrument meteorological conditions prevailed, and an instrument flight rules (IFR) flight plan had been filed. The primary wreckage was at 39 degrees 17 minutes north latitude and 120 degrees 20 minutes west longitude.

The National Transportation Safety Board investigator-in-charge (IIC) reviewed recorded radar data and noted a secondary 4271 discreet beacon code at a mode C reported altitude of 4,600 feet msl (mean sea level). Recorded radar data indicated that the airplane took off from RNO and executed the Mustang 6 departure (standard instrument departure procedure (SID)). The airplane climbed on a westerly course for about 18 minutes 30 seconds, and obtained a mode C reported altitude of 16,100 feet msl.

The radar data indicated the airplane leveled off and maintained 16,100 feet msl for about 3 minutes 40 seconds. Radar data showed the airplane initiated a climb and obtained a mode C reported altitude of 16,700 feet msl. The last 12 seconds of recorded radar data indicated the airplane was in a descent. Radar contact was lost at 18:17:29, at a mode C reported altitude of 15,700 feet msl.

During the flight, the pilot reported to air traffic controllers that he was in icing conditions and was not able to maintain altitude.

PERSONNEL INFORMATION

A review of Federal Aviation Administration (FAA) airman records revealed that the pilot held a private pilot certificate with ratings for airplane single engine land and instrument airplane.

The pilot held a third-class medical certificate issued on July 13, 2004, with a limitation that the pilot must possess corrective glasses for near vision.

An examination of the pilot's logbook indicated an estimated total flight time of 473.2 hours. He logged 100.4 hours in the last 90 days, and 38.9 hours in the last 30 days. He had an estimated 69 hours in the accident airplane make and model. He completed a biennial flight review on December 29, 2004.

AIRCRAFT INFORMATION

The airplane was a Cirrus Design SR22 G2, serial number 1235. A review of the airplane's logbooks revealed an entry for an annual inspection dated December 20, 2004. A total airframe time of 5.0 hours was reported at the last annual inspection. The Hobbs hour meter read 71.4 at the last maintenance, which was recorded in the logbook as January 23, 2005.

The engine was a Teledyne Continental Motors IO-550-N engine, serial number 917485. Total time on the engine at the last annual inspection was 5.0 hours.

Fueling records at Mercury Air Center, located at RNO, established that the airplane was last fueled on February 6, 2005. The airplane was refueled to capacity with the addition of 20.6 gallons of 100LL-octane aviation fuel. Examination of the maintenance records revealed no unresolved maintenance discrepancies against the airplane prior to departure.

The accident airplane was equipped with an Ice Protection System. This system was designed and certified for the Cirrus SR22 as a "No Hazard" to normal operations, allowing a pilot who inadvertently enters icing conditions to activate the system. Once the system is activated, deicing fluid flows along the wing, horizontal stabilizer, and propeller blades.

The Ice Protection System section of the Pilot Operating Handbook (POH) Supplements (Section 9) states in the Limitations Section that flight into known icing is prohibited. The POH further states, "no determination has been made as to the capability of this system to remove or prevent ice accumulation."

Section 3, titled Emergency Procedures, under the heading of "Inadvertent Icing Encounter" states: "Flight into known icing conditions is prohibited."

The Ice Protection System section of the POH Supplements (Section 9) also states in part:

"Flight into known icing is prohibited. The Ice Protection System has not been evaluated in known icing conditions. At the first indication of icing, the most expeditious and safest course of exiting the icing conditions should be taken."

METEOROLOGICAL INFORMATION

The closest official weather observation station was Truckee-Tahoe Airport (TRK), Truckee, California, which was located 9.3 nautical miles (nm) northeast of the accident site. The elevation of the weather observation station was 5,900 feet msl. An aviation routine weather report (METAR) for TRK was issued at 1810. It read: Winds from 240 degrees at 6 knots; visibility 10 statute miles; skies 3,400 feet broken, 10,000 feet overcast; temperature 03 degrees Celsius; dew point -03 degrees Celsius; altimeter 29.87 inHg (inches of Mercury).

The Safety Board staff meteorologist prepared a factual report, which included the following weather for the departure airport (RNO) and the nearest airport to the accident site (TRK):

Reno/Tahoe International Airport (RNO), Reno, field elevation 4,415 feet msl, located approximately 067 degrees at 29 nautical miles from the accident location, augmented Automated Surface Observation System (ASOS).

Time-1656; type-METAR; wind-calm; visibility 10 statute miles; present weather - none; sky condition - broken 11,000 feet; temperature 06 degrees Celsius; dew point -01 degree Celsius; altimeter setting 29.82 inHg; remarks - none.

Time-1756; type-METAR; wind 020 degrees at 6 knots; visibility 10 statute miles; present weather - none; sky condition - overcast 5,500 feet; temperature 06 degrees Celsius; dew point -01 degree Celsius; altimeter setting 29.83 inHg; remarks - none.

Time-1856; type-METAR; wind variable at 4 knots; visibility 10 statute miles; present weather - none; sky condition - broken 6,000 feet overcast 8,000 feet; temperature 06 degrees Celsius; dew point -03 degrees Celsius; altimeter setting 29.83 inHg; remarks-none.

COMMUNICATIONS

The pilot contacted Reno Flight Service Station (FSS) at 1620 on February 6, 2005. The pilot received a standard weather brief and filed an IFR flight plan.

The Safety Board IIC reviewed the recorded conversations between the FSS briefer and the accident pilot.

The pilot filed his IFR flight plan with a departure from RNO, via the Mustang VOR Very High Frequency Omni-directional Radio-range (FMG), airway Victor 200, to Truck intersection, airway Victor 392 to Sacramento VOR (SAC), then direct to Oakland. The pilot filed for an altitude of 12,000 feet.

The briefing included current and forecasted weather for the Reno area, the intended route of flight, and the destination. The briefer advised the pilot that there were no pilot weather reports (PIREP) for the intended route of flight. The freezing level in the Reno area was 6,000 feet with no precipitation. The pilot indicated he might request 14,000 feet once he was airborne.

The Safety Board IIC requested from the FAA transcripts of all communications between the accident pilot and any services provided by the FAA.

The FAA notified the IIC that the Digital Voice Recording System (DVRS) had malfunctioned at some point after February 3, 2005, and was not discovered until February 6, 2005. The malfunction affected the first eight channels of the DVRS, and its ability to record information on those eight channels. The eight channels included the following positions:

Channel 1 Local 1

Channel 2 Cab Coordinator

Channel 3 Ground Control

Channel 4 Local 2

Channel 5 Flight Data

Channel 6 Clearance Delivery

Channel 7 CIC

Channel 8 Final Radar

Due to this malfunction, the recordings involving the accident airplane and air traffic control (ATC) were limited to only the communications between the radar sectors and the accident airplane.

The Safety Board IIC reviewed the recordings between the pilot and Oakland Air Route Traffic Control Center (ARTCC), Sector 44. The communications between the pilot and ARTCC were on the frequency of 127.95 MHZ. All times were recorded in Coordinated Universal Time (UTC) and converted to Pacific standard time (PST).

The recording started at 1805:45, when the pilot of N286CD reported climbing out of 1,580 feet and climbing to 14,000 feet. ARTCC cleared him to continue the climb to 14,000 feet, which the pilot acknowledged.

At 1807:46, the pilot requested to continue his climb to 16,000 feet to "see if I can get above these clouds." ARTCC cleared him to 16,000 feet.

At 1812:24, N286CD was cleared to fly direct to Sacramento, which the pilot acknowledged.

At 1813:40, the pilot transmits, "Uh, I guess this isn't gonna work, I'm still in the clouds, any chance of lower?" ARTCC tells him to "stand by one."

At 1815:00, the pilot tells ARTCC that if he could go up another 200 or 300 hundred feet, he could get above the clouds. ARTCC asks the pilot, "Do you want to go up or down?" The pilot responds that he would like to go up first, "so I could build up some airspeed if that's okay."

ARTCC clears him to maintain a block altitude between 16,000 and 17,000 feet, and the pilot acknowledged.

About 2 minutes later the pilot transmits, "Uh, I'm coming down six Charlie delta (unintelligible). I'm icing up." The controller asked the pilot to repeat his transmission.

At 1817:42, the pilot makes his last transmission, stating, "I'm icing up. I'm coming down."

ARTCC then made numerous attempts to contact N286CD directly, and also requested that other airborne aircraft attempt to contact N286CD.
