## Probable cause

The improper replacement of the forward elevator trim cable, and subsequent inadequate functional check of the maintenance performed, which resulted in a reversal of the elevator trim system and a loss of control in-flight.  Factors were the flightcrew's failure to follow the checklist procedures, and the aircraft manufacturer's erroneous depiction of the elevator trim drum in the maintenance manual.

## Sequence of events

In NTSB's coding before 2008 (https://www.ntsb.gov/GILS/Documents/codman.pdf).

- Loss of control - in flight, emergency landing after takeoff
  - flt control syst,elevator trim/tab control - reversed
  - condition(s)/step(s) in error, manufacturer (contributing factor)
  - maintenance,replacement - improper, company maintenance personnel (cause)
  - maintenance,inspection - inadequate, company maintenance personnel (cause)
  - checklist - not followed, flightcrew (contributing factor)
- In flight collision with terrain/water, descent - uncontrolled
  - terrain condition - water

## Analysis

The accident flight was the first flight after maintenance personnel replaced the forward elevator trim cable.  When the flightcrew received the airplane, the captain did not address the recent cable change noted on his maintenance release.  The captain also did not perform a first flight of the day checklist, which included an elevator trim check.  Shortly after takeoff, the flightcrew reported a runway trim, and manually selected nose-up trim.  However, the elevator trim then traveled to the full nose-down position.  The control column forces subsequently increased to 250 pounds, and the flightcrew was unable to maintain control of the airplane.  During the replacement of the cable, the maintenance personnel skipped a step in the manufacturer's airliner maintenance manual (AMM).  They did not use a lead wire to assist with cable orientation.  In addition, the AMM incorrectly depicted the elevator trim drum, and the depiction of the orientation of the cable around the drum was ambiguous.  The maintenance personnel stated that they had completed an operational check of the airplane after maintenance.  The Safety Board performed a mis-rigging demonstration on an exemplar airplane, which reversed the elevator trim system.  An operational check on that airplane revealed that when the electric trim motor was activated in one direction, the elevator trim tabs moved in the correct direction, but the trim wheel moved opposite of the corresponding correct direction.  When the manual trim wheel was moved in one direction, the elevator trim tabs moved opposite of the corresponding correct direction.

## Factual narrative

HISTORY OF FLIGHT

On August 26, 2003, at 1540 eastern daylight time, a Beech 1900D, N240CJ, operated by Colgan Air Inc. as flight 9446 (d.b.a. US Airways Express), was destroyed when it impacted water near Yarmouth, Massachusetts.  The certificated airline transport pilot and certificated commercial pilot were fatally injured.  Visual meteorological conditions prevailed for the flight that departed Barnstable Municipal Airport (HYA), Hyannis, Massachusetts; destined for Albany International Airport (ALB), Albany, New York.  An instrument flight rules flight plan was filed for the repositioning flight conducted under 14 CFR Part 91.

According to data from Federal Aviation Administration (FAA) air traffic control (ATC), the flight departed runway 24 at Hyannis about 1538.  Shortly after takeoff, the flightcrew declared an emergency and reported a "runaway trim."  The airplane flew a left turn and reached an altitude of approximately 1,100 feet.  The flightcrew subsequently requested to land on runway 33, and the air traffic control tower (ATCT) controller cleared the flight to land on any runway.  No further transmissions were received from the flightcrew.

Witnesses observed the airplane in a left turn, with a nose-up attitude.  The airplane then pitched nose-down, and impacted the water "nose first."

According to the cockpit voice recorder (CVR), the flightcrew completed the Before Start checklist between 1523 and 1530; however, there was no record of the First Flight Of The Day checklist being completed after engine start.

At 1523:30, the captain called for the Before Start checklist.

At 1523:43, the first officer stated, "preflight's complete.  cockpit scan complete."  The captain replied, "complete."

At 1523:58, the first officer stated, "maintenance log, release, checked the aircraft."  The captain replied, "uhhhh.  maintenance and release on aircraft.  The captain subsequently identified that the DFDR was inoperative, and confirmed that the minimum equipment list (MEL) was still open.

At 1525:11, the captain began to start the right engine, before being interrupted.  Approximately 1 minute later, after a conversation with maintenance personnel over the radio, the captain resumed the starting of the right engine.

At 1529:29, as the captain was starting the left engine, the flightcrew began non-pertinent conversation, which lasted about 30 seconds.

At 1530:04, the captain called for the After Start checklist.  After completing the After Start checklist items, the first officer announced the checklist "complete."

At 1530:21, the captain continued the previous non-pertinent conversation, followed 10 seconds later with, "all right we're ready to taxi with HOTEL."

At 1530:50, the flightcrew began a conversation about the flight plan to ALB, taxiing the airplane, and which pilot would fly the airplane.  The conversation lasted for about 4 minutes.

At 1535:14, during the Taxi checklist, the first officer stated, "...three trims are set."  The first officer then called the Taxi checklist "complete."

At 1535:26, the flight crew began a non-pertinent discussion about a landing airplane.  The discussion lasted about 1 minute and 27 seconds.

At 1537:00, the airplane was holding short of runway 24.

At 1537:17, the captain stated, "all right.  forty six is ready."  The flightcrew then began to announce several items, which were identified as being on the Before Takeoff checklist; however, the checklist was not called for.

At 1538:07, the controller cleared Colgan flight 9446 for takeoff on runway 24.

At 1538:08, the flightcrew initiated a takeoff on runway 24.

At 1538:40, the first officer stated "V1...rotate."

At 1538:46, the captain stated, "...we got a hot trim..."  At that time, according to the digital flight data recorder (DFDR), the elevator trim moved from approximately -1.5 degrees (nose down) to -3 degrees at a speed consistent with the electric trim motor.

At 1538:48, the captain stated, "kill the trim kill the trim kill the trim."

At 1538:50, the captain stated, "roll back...roll back roll back roll back roll back."  According to the DFDR, the elevator trim then moved from approximately -3 degrees to -7 degrees at a speed greater than the capacity of the electric trim motor.

At 1538:56, the captain stated, "roll it back roll my trim..."

At 1539:00, the captain stated, "do the electric trim disconnect..."

At 1539:04, the captain instructed the first officer to, "go on the controls" with him.

At 1539:14, the captain instructed the first officer to retract the landing gear.

At 1539:18, the captain instructed the first officer to retract the flaps.  The first officer responded that they were "up."

At 1539:21, the captain declared an emergency regarding a runaway trim and requested to return to the airport.  The controller acknowledged the emergency and offered the option of the left or right downwind for runway 24.

At 1539:33, the captain instructed the first officer to reduce the engine power.

From 1539:49 to 1540:03, the captain instructed the first officer to "pull the breaker."  The first officer queried the captain as to its location.

At 1540:30, the captain requested to land on runway 33.  The controller acknowledged the transmission and cleared the flight to land on runway 33.

The recording ended at 1540:47.

The accident occurred during the hours of daylight; located approximately 41 degrees, 37 minutes north longitude, and 70 degrees, 15 minutes west latitude.
