AGENCY:

Federal Aviation Administration (FAA), DOT.

ACTION:

Final rule; request for comments.

SUMMARY:

The FAA is adopting a new airworthiness directive (AD) that applies to all Raytheon Aircraft Company (Raytheon) Beech Models 1900, 1900C, and 1900D airplanes. This AD requires you to make a correction to the elevator trim system maintenance procedures, incorporate a temporary revision to the applicable maintenance manual, and incorporate procedures that will enhance the existing elevator trim operational check every time you have maintenance done on the elevator trim system. This AD is the result of an analysis of the maintenance procedures of the elevator trim system. We are issuing this AD to detect and correct any maintenance-induced problems with the elevator trim system installation before problems occur during operation. Such a condition could lead to difficulties in controlling the airplane or a total loss of pitch control.

DATES:

This AD becomes effective on October 15, 2003.

The Director of the Federal Register approved the incorporation by reference of certain publications listed in the regulation as of October 15, 2003.

We must receive any comments on this AD by December 7, 2003.

Discussion

What Events Have Caused This AD?

On August 26, 2003, a Raytheon Model Beech 1900D twin-turboprop airplane was involved in an accident in the Nantucket Sound off southeastern Massachusetts. The Raytheon Beech Model 1900D is designed to carry 19 passengers. According to initial reports, the airplane took off of Runway 24 at Barnstable Municipal Airport on Cape Cod. The pilot immediately declared an emergency and, while en route to make an emergency landing on Runway 33, crashed into the water.

While there is no determination of the cause of the accident and the investigation is ongoing, FAA's review of the current maintenance procedures of the elevator trim system reveals the following:

—The figures in the applicable maintenance manuals depict the elevator trim cable drum at 180 degrees from the installed position and show the open, keyed side of the drum instead of the flat side of the drum. Following these figures when installing the control cables on the forward control cable drum could reverse the action of the elevator manual trim system; and

—The existing procedure can be enhanced by visually confirming the trim wheel position and the trim tab position are consistent. Such a check would detect and correct any problems with the elevator trim system installation before problems occur during operation.

Although the figures (figure 9 for the 1900/1900C and figure 201 for the 1900D) in the existing maintenance manuals are incorrectly depicted, following the step-by-step written instructions in the existing procedure and referring to the orientation of the parts removed would result in the correct installation and action of the elevator trim system.

What Are the Consequences if the Condition Is Not Corrected?

An incorrectly installed elevator trim system component, if not detected and corrected, could result in difficulties in controlling the airplane or a total loss of pitch control.

Is There Service Information That Applies to This Subject?

Raytheon has issued Safety Communiqué No. 234, dated September 2003, to address this issue.

What Are the Provisions of This Service Information?

The safety communiqué includes information about the incorrect depictions of the figures in the applicable maintenance manuals and also references the following temporary maintenance manual revisions:

—Temporary Revision No. 27-5 to the Model 1900/1900C Airliner Maintenance Manual: Revised ELEVATOR TRIM OPERATIONAL CHECK; and

—Temporary Revision No. 27-9 to the Model 1900D Airliner Maintenance Manual: Added MANUAL ELEVATOR TRIM OPERATIONAL CHECK.

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 this same type design.

Since the unsafe condition described previously is likely to exist or develop on other Raytheon Beech Models 1900, 1900C, and 1900D airplanes of the same type design, this AD is being issued to detect and correct any maintenance-induced problems with the elevator trim system installation before problems occur during operation. Such a condition could lead to difficulties in controlling the airplane or a total loss of pitch control.

What Does This AD Require?

This AD requires you to:

—Make a correction to the elevator trim system maintenance procedures;

—Incorporate a temporary revision to the applicable maintenance manual; and

—Incorporate procedures that will enhance the existing elevator trim operational check every time you have maintenance done on the elevator trim system.Start Printed Page 58579

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 Prior to the Issuance of 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 “AD Docket No. 2003-CE-43-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 will consider all comments received by the closing date and may amend the AD in light of those comments.

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 No. 2003-CE-43-AD” in your request.
