Aviation Accident Summary CHI89LA146

NAPPANEE, IN, USA

Aircraft #1

N3923F

PIPER PA-32R-300

Analysis

WHILE ATTEMPTING TO TAKEOFF ON A PART 135 CARGO FLIGHT, THE PILOT OBSERVED THAT THE AIRPLANE WAS NOT DEMONSTRATING A POSITIVE RATE OF CLIMB. HE ABORTED THE TAKEOFF, BUT WAS UNABLE TO STOP THE AIRPLANE ON THE RUNWAY. IT CONTINUED ACROSS A FIELD, ROADWAY, AND DITCH, SEPARATING THE LEFT WING FROM THE AIRPLANE. POST- ACCIDENT EVALUATION REVEALED 4 OF THE 6 CYLINDERS TO HAVE INADEQUATE COMPRESSION, THE MAXIMUM GROSS WEIGHT WAS EXCEEDED, AND THE CENTER OF GRAVITY WAS AFT OF ACCEPTABLE LIMITS.

Probable Cause and Findings

THE PILOT-IN-COMMAND'S IMPROPER PREFLIGHT CALCULATION OF WEIGHT AND BALANCE AND THE AIRCRAFT'S INADEQUATE CLIMB CAPABILITY DUE TO LOW COMPRESSION.
