AD NUMBER: 2004-17-01
MANUFACTURER: Cessna (CORRECTION) SUBJECT: Airworthiness Directive 2004-17-01 SUMMARY: The FAA supersedes Airworthiness
Directive (AD) AD 2002-22-17, which applies to all Cessna Aircraft
Company (Cessna) Models 208 and 208B airplanes; and AD 2003-21-04,
which applies to certain Cessna Models 208 and 208B airplanes. This
AD requires you to repetitively inspect the flap bell cranks for
cracks and eventually replace these bell cranks. The installation
of a newly designed bell crank to increase the life limits is
terminating action for the repetitive inspections. This AD is the
result of these developments: Since FAA issued AD 2002-22-17 and AD
2003-21-04, Cessna designed a new flap bell crank with a life limit
of 40,000 landings instead of 7,000 landings. Also, FAA has done
more analysis and examination of cracks and missing/incomplete
welds in all of the bell cranks. This failure could lead to damage
to the flap system and surrounding structure and result in reduced
or loss of control of the airplane.The FAA supersedes Airworthiness
