Start Preamble

AGENCY:

Federal Aviation Administration (FAA), DOT.

ACTION:

Final rule; request for comments.

SUMMARY:

The FAA is adopting a new airworthiness directive (AD) for all The Cessna Aircraft Company (Cessna) Models 208 and 208B airplanes. This AD requires you to incorporate information into the applicable section of the Airplane Flight Manual (AFM). This AD results from several accidents/incidents of problems with the affected airplanes during operations in icing conditions, including six accidents in the previous two icing seasons and nine events in the past few months. We are issuing this AD to assure that the pilot has enough information to prevent loss of control of the airplane while in-flight during icing conditions.

DATES:

This AD becomes effective on March 29, 2005.

We must receive any comments on this AD by April 30, 2005.

End Further Info End Preamble Start Supplemental Information

SUPPLEMENTARY INFORMATION:

What events have caused this AD? The FAA has received several reports of accidents/incidents concerning problems with Cessna Models C208 and C208B airplanes during operations in icing conditions. This includes a total of six accidents in the previous two icing seasons and nine events in the past few months. Most of the accidents occur on approach and landing. One-third are suspected to be in supercooled large droplets, icing conditions outside the 14 CFR part 25 Appendix C certification envelope. The Cessna Models C208 and C208B are certificated to 14 CFR part 23, but 14 CFR part 23 references 14 CFR part 25 Appendix C for icing certification. The following chart shows the monthly breakdown of the icing accidents/incidents of the affected airplanes:

Start Printed Page 15224

The information shows that icing accidents/incidents are just as prevalent or more prevalent during the months of March and April than in November, December, and January. Therefore, the next month is critical for the continued operational safety of the Cessna Models C208 and C208B in icing conditions.

What is the potential impact if FAA took no action? If the pilot does not have enough information on flight into icing conditions in the Airplane Flight Manual (AFM), then loss of control of the airplane could occur.

Is there service information that applies to this subject? Cessna has developed revisions to the FAA-approved AFM to address this issue, as follows:

DocumentAffects
Temporary Revision 208PHTR04, dated March 2, 2005, to the FAA-approved Airplane Flight ManualCessna Model 208, all models and serial numbers.
Revision 5 of of the 208 (675 SHP) FAA-approved Flight Supplement 1 “Known Icing Equipment”, Cessna document D1352-S1-05, dated March 2, 2005Cessna Model C208 airplanes with a Pratt & Whitney Canada Ltd., PT6A-114A turboprop engine installed (675 SHP) or FAA-approved engine of equivalent horsepower installed, except airplanes modified by Supplemental Type Manual Certificate SA00892WI.
Revision 5 of of the 208 (600 SHP) FAA-approved Flight Manual Supplement S1 “Known Icing Equipment”, Cessna document D1307-S1-05, dated March 2, 2005Cessna Model C208 airplanes with a Pratt & Whitney Canada Ltd., PT6A-114 turboprop engine installed (600 SHP) or FAA-approved engine of equivalent horsepower approved installed, except airplanes modified by Supplemental Type Certificate SA00892WI.
Revision 6 of the 208B (675 SHP) FAA-approved Flight Manual Supplement S1 “Known Icing Equipment”, Cessna document D1329-S1-06, dated March 2, 2005Cessna Model C208B airplanes with a Pratt & Whitney of Canada Ltd., PT6A-114A turboprop engine installed (675 SHP) or FAA-approved engine of equivalent horsepower installed, except airplanes modified by Supplemental Type Certificate SA00892WI.
Revision 5 of the 208B (600 SHP) FAA-approved Flight Manual Supplement S1 “Known Icing Equipment”, Cessna document D1309-S1-05, dated March 2, 2005Cessna Model C208B airplanes with a Pratt & Whitney of Canada Ltd., PT6A-114 turboprop engine installed (600 SHP) or FAA-approved engine of equivalent horsepower installed, except airplanes modified by Supplemental Type Certificate SA00892WI.

FAA's Determination and Requirements of the 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 the same type design.

Since the unsafe condition described previously is likely to exist or develop on other type design Cessna Models C208 and C208B airplanes, we are issuing this AD to assure that the pilot has enough information to prevent loss of control of the airplane while in-flight during icing conditions. Start Printed Page 15225

What does this AD require? This AD requires you to incorporate the above-referenced documents into the AFM.

In preparing this rule, we contacted type clubs and aircraft operators to get technical information and information on operational and economic impacts. We did not receive any information through these contacts that influenced our decision. The majority of the respondents supported the dissemination of the information in the revised AFM.

How does the revision to 14 CFR part 39 affect this 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.

Comments Invited

Will I have the opportunity to comment before you issue the rule? This AD is a final rule that involves requirements affecting flight safety and was not preceded by notice and an opportunity for public comment; however, we invite you to submit any written relevant data, views, or arguments regarding this AD. Send your comments to an address listed under ADDRESSES. Include “Docket No. FAA-2005-20514; Directorate Identifier 2005-CE-08-AD” in the subject line of your comments. If you want us to acknowledge receipt of your mailed comments, send us a self-addressed, stamped postcard with the docket number written on it; we will date-stamp your postcard and mail it back to you. We specifically invite comments on the overall regulatory, economic, environmental, and energy aspects of the rule that might suggest a need to modify it. If a person contacts us through a nonwritten communication, and that contact relates to a substantive part of this AD, we will summarize the contact and place the summary in the docket. We will consider all comments received by the closing date and may amend the AD in light of those comments.

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

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

Will this AD involve a significant rule or regulatory action? For the reasons discussed above, I certify that this 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 AD 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-2005-20514; Directorate Identifier 2005-CE-08-AD” in your request.

[Docket No. FAA-2005-20514; Directorate Identifier 2005-CE-08-AD]

Preflight

Takeoff is prohibited with any frost, ice, snow, or slush adhering to the wings, horizontal stabilizer, control surfaces, propeller blades, and engine inlets.

Warning

Even small amounts of frost, ice, and snow, or slush on the wing may adversely change lift and drag. Failure to remove these contaminants will degrade airplane performance and may prevent a safe takeoff and climbout.

Visual/Tactile Check

In addition to a visual check, a tactile check of the wing leading edge, wing upper surface (up to two feet behind the deicing boot at on-span location as a minimum), horizontal tail leading edge, and propeller Start Printed Page 15227blades is required if the outside air temperature (OAT) is below 5° C (41° F) and visible moisture (rain, drizzle, sleet, snow, fog etc.) is present or the airplane was exposed to visible moisture (rain, drizzle, sleet, snow, fog etc.) since the previous landing; or the airplane experienced in-flight ice accretion since the previous takeoff; or the difference between the dew point temperature and the OAT is 3° C (5° F) or less; or water is present on the wing. Reference the preflight procedures in Section 4 of the basic Pilot's Operating Handbook.
