Airworthiness Directives; The Cessna Aircraft Company Models 208 and 208B Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Notice of proposed rulemaking (NPRM).

SUMMARY: The FAA proposes to adopt a new airworthiness directive (AD) for all The Cessna Aircraft Company (Cessna) Models 208 and 208B airplanes. This proposed AD would require you to install a pilot assist handle, Cessna part number SK208-146-2, for all affected airplanes, install deicing boots on landing gear struts and cargo pod on certain Cessna Models 208 and 208B airplanes, and make changes to the Pilot's Operating Handbook (POH) and FAA-approved Airplane Flight Manual (AFM), and to the POH and AFM Supplement S1 for all affected airplanes. This proposed AD results from reports of several accidents and of problematic events involving the affected airplanes during operations in icing conditions, including nine events in the 2004-2005 icing season, and ground icing conditions. We are issuing this proposed AD to prevent ice adhering to critical surfaces. Ice adhering to critical surfaces could result in a reduction in airplane performance with the consequences that the airplane cannot perform a safe takeoff, climb, or maintain altitude.

DATES: We must receive any comments on this proposed AD by August 22, 2005.

Discussion

What events have caused this proposed AD? The FAA has received several reports of accidents and incidents concerning problems with Cessna Models 208 and 208B airplanes during operations in icing conditions. This includes a total of six accidents in the previous two icing seasons and nine incidents in the past few months. One-third of the Model 208 icing related accidents occurred as a result of loss of control after takeoff in ground icing conditions. One-third are suspected to

[[Page 35566]]

have occurred in supercooled large droplets, icing conditions outside the 14 CFR part 25 Appendix C certification envelope. The Cessna Models 208 and 208B are certificated to 14 CFR part 23, but 14 CFR part 23 references 14 CFR part 25 Appendix C for icing certification.

Findings from the accidents conclude that there was a reduction in airplane performance due to drag from airframe ice accretion. The airplanes could not perform a safe takeoff, climb, or maintain altitude.

What is the potential impact if FAA took no action? Ice adhering to critical surfaces could result in a reduction in airplane performance with the consequence that the airplane cannot climb or maintain altitude.

Is there service information that applies to this subject? Cessna has issued the following service information:

--Service Bulletin No. CAB04-9, dated October 4, 2004; --Service Kit No. SK208-146, dated October 4, 2004; --Service Bulletin No. CAB95-19, dated October 13, 1995; --Service Bulletin No. CAB93-20, Revision 1, dated October 13, 1995; and --Accessory Kit No. AK208-6C, issued December 2, 1991, Revision C, dated August 27, 1993.

What are the provisions of this service information? The service information includes procedures for:

--Adding a low airspeed in icing warning system, a windshield ice indicator assembly, a pilot assist handle, and an enlarged windshield anti-ice panel; and --Installing cargo pod and landing gear deice system.

FAA's Determination and Requirements of this Proposed AD

What has FAA decided? We have evaluated all pertinent information and identified an unsafe condition that is likely to exist or develop on other products of this same type design. For this reason, we are proposing AD action.

What would this proposed AD require? This proposed AD would require you to:

--Install the pilot assist handle (part number (P/N) SK208-146-2) for all Cessna Models 208 and 208B airplanes; --Install Cessna Accessory Kit AK208-6C for all Cessna Models 208 and 208B airplanes equipped with pneumatic deicing boots for flight into known icing; and --Make changes to the Pilot's Operating Handbook ( POH) and FAA- approved Airplane Flight Manual (AFM), and to the POH and AFM Supplement S1.

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 743 airplanes in the U.S. registry.

What would be the cost impact of this proposed AD on owners/ operators of the affected airplanes? We estimate the following costs to do the proposed installation of the pilot assist handle (P/N SK208-146- 2) for all Cessna Models 208 and 208B airplanes:

Total cost per Labor cost

Parts cost airplane

Total cost on U.S. operators

5 work hours x $65 = $325..................

$858

$1,183 743 x $1,183 = $878,969

We estimate the following costs to do the proposed installation of the Cessna Accessory Kit AK208-6C for certain Cessna Modes 208 and 208B:

Total cost per Labor cost

Parts cost airplane

Total cost on U.S. Operators

37 work hours x $65 = $2,405...............

$6,000

$8,405 372 x $8,405 = $3,126,660

We estimate the following costs to do the proposed changes to the Pilot's Operating Handbook (POH) and FAA-approved Airplane Flight Manual (AFM), and to the POH and AFM Supplement S1:

Total cost per Labor cost

Parts cost

airplane Total cost on U.S. operators

1 work hour x $65 = $65............... Not Applicable...........

$65 743 x $65 = $48,295

Authority for This Rulemaking

What authority does FAA have for issuing this rulemaking action? Title 49 of the United States Code specifies the FAA's authority to issue rules on aviation safety. Subtitle I, Section 106 describes the authority of the FAA Administrator. Subtitle VII, Aviation Programs, describes in more detail the scope of the agency's authority.

We are issuing this rulemaking under the authority described in Subtitle VII, Part A, Subpart III, Section 44701, ``General requirements.'' Under that section, Congress charges the FAA with promoting safe flight of civil aircraft in air commerce by prescribing regulations for practices, methods, and procedures the Administrator finds necessary for safety in air commerce. This regulation is within the scope of that authority because it addresses an unsafe condition that is likely to exist or develop on products identified in this AD.

Regulatory Findings

Would this proposed AD impact various entities? We have determined that this proposed AD would not have federalism implications under Executive Order 13132. This proposed AD would not have a substantial direct effect on

[[Page 35567]]

the States, on the relationship between the National Government and the States, or on the distribution of power and responsibilities among the various levels of government.

Would this proposed AD involve a significant rule or regulatory action? For the reasons discussed above, I certify that this proposed AD:

1. Is not a ``significant regulatory action'' under Executive Order 12866;

2. Is not a ``significant rule'' under the DOT Regulatory Policies and Procedures (44 FR 11034, February 26, 1979); and

3. Will not have a significant economic impact, positive or negative, on a substantial number of small entities under the criteria of the Regulatory Flexibility Act.

   We prepared a summary of the costs to comply with this proposed AD (and other information as included in the Regulatory Evaluation) and placed it in the AD Docket. You may get a copy of this summary by sending a request to us at the address listed under ADDRESSES. Include ``AD Docket FAA-2005-21275; Directorate Identifier 2005-CE-28-AD'' in your request.

   List of Subjects in 14 CFR Part 39

   Air transportation, Aircraft, Aviation safety, Safety.

   The Proposed Amendment

   Accordingly, under the authority delegated to me by the Administrator, the Federal Aviation Administration proposes to amend 14 CFR part 39 as follows:

   PART 39--AIRWORTHINESS DIRECTIVES

1. The authority citation for part 39 continues to read as follows:

   Authority: 49 U.S.C. 106(g), 40113, 44701.

   Sec. 39.13 [Amended]

2. The FAA amends Sec. 39.13 by adding the following new airworthiness directive (AD):

   The Cessna Aircraft Company: Docket No. FAA-2005-21275; Directorate Identifier 2005-CE-28-AD

   When Is the Last Date I Can Submit Comments on This Proposed AD?

   (a) We must receive comments on this proposed airworthiness directive (AD) by August 22, 2005.

   What Other ADs Are Affected by This Action?

   (b) None.

   What Airplanes Are Affected by This AD?

   (c) This AD affects Models 208 and 208B, all serial numbers, that are certificated in any category.

   What Is the Unsafe Condition Presented in This AD?

   (d) This AD is the result of reports of several accidents and of problematic events involving the affected airplanes during operations in icing conditions, including nine events in the 2004- 2005 icing season, and ground icing conditions. The actions specified in this AD are intended to prevent ice adhering to critical surfaces. Ice adhering to critical surfaces could result in a reduction in airplane performance, with the consequence that the airplane cannot perform a safe takeoff, climb, or maintain altitude. The pilot assist handle will allow a pre-takeoff visual/tactile check of the wing upper surface to be safely conducted in ground icing conditions.
