Aviation Accident Summary CEN10CA341

Albuquerque, NM, USA

Aircraft #1

N9849C

CESSNA R182RG

Analysis

During the initial climb, the pilot noticed the airspeed indicator was erratic and not indicating a normal climb speed. After leveling off, the indicated airspeed was 70 to 80 knots. He compared this with the GPS (Global Positioning System) ground speed and noticed a "significant difference." Later, while circling a house, the airspeed "went to zero knots." The pilot returned for landing and mentally went through the GUMPs (gas, undercarriage, mixture, prop) checklist, but was distracted by the airspeed indicator and radio traffic. As he flared for landing and reduced power, he heard a horn sounding and mistook it for the marker beacon alert. The airplane landed wheels up. An examination of the pitot tube showed it was plugged with insects. No other anomalies were found.

Factual Information

According to the pilot's accident report, during the initial climb from Albuquerque Sunport (ABQ), New Mexico, he noticed the airspeed indicator was erratic and not indicating a normal climb speed. After leveling off, the indicated airspeed was 70 to 80 knots. He compared this with the GPS (Global Positioning System) ground speed and noticed a "significant difference." Later, while circling a house, the airspeed "went to zero knots." The pilot returned for landing at ABQ. He said he mentally went through the GUMPs (gas, undercarriage, mixture prop) checklist but was distracted by the airspeed indicator and radio traffic. As he flared for landing and reduced power, he heard a horn sounding and mistook it for the marker beacon alert. The airplane landed wheels up. A post-accident examination revealed the airplane's fuselage skin and U-shaped former (where the lift struts attach) were ground down, necessitating replacement. An examination of the pitot tube showed it was plugged with insects.

Probable Cause and Findings

The pilot's failure to lower the landing gear. Contributing to the accident was the pilot's distraction with an erroneous airspeed indicator.
