NTSB PRESS RELEASE ************************************************************ National
Transportation Safety Board Washington, DC
20594 FOR IMMEDIATE
RELEASE: October 14, 2009 SB-09-57 ************************************************************ PILOT
MISMANAGEMENT AND IMPROPER ACTIONS CAUSED MEDICAL FLIGHT CRASH NEAR
MILWAUKEE, NTSB DETERMINES ************************************************************ Washington, D.C.
- The National Transportation Safety Board today determined
that the probable cause of an aircraft that lost control and
impacted water was the pilots' mismanagement of
an abnormal flight control situation through improper
actions, including lack of crew coordination, and
failing to control airspeed and to prioritize
control of the airplane. On June 4, 2007,
about 4:00pm CST, a Cessna Citation 550, N550BP, impacted
Lake Michigan shortly after departure from General Mitchell
International Airport, Milwaukee, Wisconsin (MKE). The two
pilots and four passengers were killed, and the airplane was
destroyed. The airplane was being operated by Marlin Air
under the provisions of Part 135. The aircraft was carrying a
human organ for a transplant operation in Michigan. At the
time of the accident, marginal visual meteorological
conditions prevailed at the surface, and instrument
meteorological conditions prevailed aloft; the flight operated
on an instrument flight rules flight plan. Due to the lack
of a data recording system, the Board could not determine the
exact nature of the initiating event of the accident.
However, the evidence indicated that the two most likely
scenarios were a runaway trim or the inadvertent engagement of the
autopilot, rather than the yaw damper, at takeoff. The Board further
noted that the event was controllable if the captain had
not allowed the airspeed and resulting control forces to
increase while he tried to troubleshoot the problem. By
allowing the airplane's airspeed to increase while
engaging in poorly coordinated troubleshooting
efforts, the pilots allowed an abnormal situation to
escalate to an emergency. Therefore, the
NTSB concluded that if the pilots had simply maintained a
reduced airspeed while they responded to the situation, the
aerodynamic forces on the airplane would not have increased
significantly. At reduced airspeeds, the pilots should
have been able to maintain control of the airplane long
enough to either successfully troubleshoot and resolve the
problem or return safely to the airport. Contributing to
the accident were Marlin Air's operational safety
deficiencies, including the inadequate checkrides administered by
Marlin Air's chief pilot/check airman, and the Federal
Aviation Administration's (FAA) failure to detect and
correct those deficiencies, which placed a pilot who inadequately
emphasized safety in the position of company chief
pilot and designated check airman and placed an ill-prepared
pilot in the first officer's seat. Results from the
Board's investigation indicated that the captain did not
adhere to procedures or comply with regulations, and
that he routinely abbreviated checklists. Subsequently, the
NTSB concluded that the pilots' lack of discipline, lack
of in-depth systems knowledge, and failure to adhere to
procedures contributed to their inability to cope with
anomalies experienced during the accident flight. Thus, the Board
also concluded that Marlin Air's selection of a chief
pilot/check airman who failed to comply with procedures and
regulations contributed to a culture that allowed an
ill-prepared first officer to fly in Part 135 operations. The report
adopted today by the Board, points out that FAA guidance
regarding appointment of check airmen requires Principal
Operations Inspectors (POI) to verify the check airman
candidate's "certificates and background." Additionally, all
required training must be completed, and the airman's
training records must show satisfactory completion of
initial, transition, or upgrade training, as applicable. The
guidance does not specifically address POI actions when the
background evaluation discloses negative information. This
lack of guidance can result in the appointment of
check airmen who do not adhere to standards and who possibly
jeopardize flight safety. As a result of
this accident investigation, the Safety Board issued
recommendations to the FAA, and the American Hospital Association
regarding airplane and system deficiencies, FAA oversight, and
the safety ramifications of an operator's financial health. -30- A summary of the
findings of the Board's report is available on the NTSB's
