Airworthiness Directives; Cessna Aircraft Company Models 208 and 208B Airplanes
AGENCY: Federal Aviation Administration (FAA), DOT.
ACTION: Supplemental notice of proposed rulemaking (NPRM); reopening of the comment period.
SUMMARY: The FAA proposes to revise an earlier NPRM airworthiness directive (AD) action that applies to certain Cessna Aircraft Company (Cessna) Models 208 and 208B airplanes. That proposed AD would have revised AD 2002-22-17, which currently requires you to repetitively inspect the inboard forward flap bellcranks for cracks and eventually replace these bellcranks on all Cessna Models 208 and 208B airplanes. The proposed AD would have provided the option of installing a newly designed bellcrank to increase the life limits and terminate the repetitive inspections. AD 2003-21-04 also requires inspections of the inboard forward flap bellcranks on these airplanes. The FAA has determined that additional inspections of the bellcranks are necessary on Cessna Models 208 and 208B airplanes. We believe that it would be less confusing if all of these actions were in one AD. Therefore, FAA proposes to supersede AD 2002-22-17 and AD 2003-21-04. Since the added actions from AD 2003-21-04 and other proposed inspections impose an additional burden over that proposed in the NPRM, we are reopening the comment period to allow the public the chance to comment on these additional actions.
DATES: We must receive any comments on this proposed AD by May 17, 2004.
ADDRESSES: Use one of the following to submit comments on this proposed AD:

Discussion
What Events Have Caused This Proposed AD?
The need to reduce the life limit and repetitively inspect the inboard forward flap bellcrank on Cessna Models 208 and 208A airplanes caused us to issue AD 2002-22-17, Amendment 29-12944 (67 FR 68508, November 12, 2002).
Since FAA issued AD 2002-22-17, Cessna has designed a new flap bellcrank, part number (P/N) 2622311-7, with a life limit of 40,000 landings (instead of 7,000 landings). The new flap bellcrank (P/N 2622311-7) may be substituted for the older flap bellcranks, P/N 2622281-2, 2622281-12, or 2692001-2. Installation of this new flap bellcrank will eliminate the need for repetitive inspections.
Has FAA Taken Any Action to This Point?
We issued a proposal to amend part 39 of the Federal Aviation Regulations (14 CFR part 39) to include an AD that would apply to all Cessna Models 208 and 208B airplanes. This proposal was published in the Federal Register as a notice of proposed rulemaking (NPRM) on July 28, 2003 (68 FR 44252). The NPRM proposed to revise AD 2002-22-17 by proposing a new AD that would:
--Retain the requirements of AD 2002-22-17; and --Provide the option of installing the 40,000 landings life limit bellcranks.
Was the Public Invited To Comment?
The FAA encouraged interested persons to participate in developing this amendment. We did not receive any comments on the proposed rule or on our determination of the cost to the public.
What Events Have Caused FAA To Issue a Supplemental NPRM?
The FAA recently issued AD 2003-21-04, Amendment 39-13339 (68 FR 59707, October 17, 2003) to require you to immediately inspect certain inboard forward flap bellcranks for cracks, deformation, and missing/ incomplete welds. If cracks, deformation, or missing/incomplete welds are found, the AD would require you to immediately replace the flap bellcrank or temporarily incorporate certain flap limitations.
In addition, FAA has identified other bellcranks within the flap system that require inspection. The FAA has determined that all of the inspections and replacements of the bellcranks should be included in one AD. These inspections are referenced in Cessna Caravan Service Bulletin CAB03-11, Revision 1, dated September 24, 2003.
FAA's Determination and Requirements of This Proposed AD
What Has FAA Decided?
After examining the circumstances and reviewing all available information related to the incidents described above, we have determined that: --The unsafe condition referenced in this document exists or could develop
[[Page 10642]]
on other Cessna Models 208 and 208B airplanes of the same type design that are on the U.S. registry; --We should combine the actions of AD 2002-22-17, AD 2003-21-04, and those referenced in Cessna Caravan Service Bulletin CAB03-11, Revision 1, dated September 24, 2003; and --We should take AD action to correct this unsafe condition.
The Supplemental NPRM
How Will the Changes to the NPRM Impact the Public?
Adding the inspection and replacement requirements from both AD 2003-21-04 and Cessna Caravan Service Bulletin CAB03-11, Revision 1, dated September 24, 2003, goes beyond the scope of what was originally proposed in the NPRM. Therefore, we are reopening the comment period and allowing the public the chance to comment on these additional actions.
What Are the Provisions of the Supplemental NPRM?
The proposed AD would supersede AD 2002-22-17 and AD 2003-21-04 by requiring you to: --Do all current requirements of AD 2002-22-17; --Provide the option of installing the 40,000 landings life limit bellcranks; --Inspect all bellcranks for cracks, deformation, and missing/ incomplete welds; and --If cracks, deformation, or missing/incomplete welds are found, the AD would require you to immediately replace the bellcrank or temporarily incorporate certain flap limitations.
How Does the Revision to 14 CFR Part 39 Affect This Proposed AD?
On July 10, 2002, we published a new version of 14 CFR part 39 (67 FR 47997, July 22, 2002), which governs FAA's AD system. This regulation now includes material that relates to altered products, special flight permits, and alternative methods of compliance. This material previously was included in each individual AD. Since this material is included in 14 CFR part 39, we will not include it in future AD actions.
Costs of Compliance
How Many Airplanes Would This Proposed AD Impact?
We estimate that this proposed AD affects 1,300 airplanes in the U.S. registry.
What Would Be the Cost Impact of This Proposed AD on Owners/Operators of the Affected Airplanes?
For the proposed actions retained from AD 2003-21-04, and the addition of all bellcranks to the applicability, we estimate the following costs to do this proposed inspection:
Total cost Labor cost
Parts cost

We estimate the following costs to do any necessary replacements of the right inboard forward flap bellcrank (P/N 2622311-7, alternate P/N 2622311-16) that would be required based on the results of this proposed inspection. We have no way of determining the number of airplanes that may need this replacement:

We estimate the following costs to do any proposed replacements using the new flap bellcrank (P/N 2622311-7 or FAA-approved equivalent P/N) that will be required based on the proposed inspection or the reduced life limits. We have no way of determining the number of airplanes that may need this proposed replacement with the new flap bellcrank:
Labor cost
Parts cost
Total cost per airplane
3 workhours x $65 per hour = $195............... $1,845 $195 + $1,845 = $2,040.
What Is the Difference Between the Cost Impact of This Proposed AD and the Cost Impacts of AD 2003-21-04 and AD 2002-22-17?
AD 2003-21-04 already established the inspection and replacement of the right inboard forward flap bellcrank assembly on the affected airplanes. Therefore, the replacement is already required through that AD. The only difference in the cost impact on the public of this proposed AD and AD 2003-21-04 is the additional cost for the inspection of all other bellcranks, and, if necessary, replacement.
AD 2002-22-17 already established the life limit for the flap bellcrank (P/N 2622281-2, 2622281-12, 2692001-2, or FAA-approved equivalent P/N) on the affected airplanes. Therefore, the replacement is already required through that AD. The only difference in the cost impact upon the public of this AD and AD 2002-22-17 is the additional $52 cost difference for the new flap bellcrank.

Note 1: Inboard forward flap bellcranks (P/N 2622281-2, 2622281- 12, or 2692001-2) with 7,000 landings or more do not have to be replaced until 75 landings after December 31, 2002 (the effective date of AD 2002-22-17), unless found cracked.
Note 2: The compliance times of this AD are presented in landings instead of hours TIS. If the number of landings is unknown, hours TIS may be used by multiplying the number of hours TIS by 1.25.
What Are the Actions I Must Do if I Choose the Flap Prohibition Option?
(g) Insert Temporary Revision, 208PHTR02, dated September 23, 2003, into the applicable pilot's operating handbook and FAA- approved airplane flight manual. The owner/operator holding at least a private pilot certificate as authorized by Sec. 43.7 of the Federal Aviation Regulations (14 CFR 43.7) may incorporate this information into the AFM.
