Start Preamble

AGENCY:

Federal Aviation Administration, DOT.

ACTION:

Notice of proposed rulemaking (NPRM).

SUMMARY:

This document proposes to adopt a new airworthiness directive (AD) that would apply to certain Raytheon Aircraft Company (Raytheon) Model 58P, 60, A60, B60, and 65-88 airplanes. This proposed AD would require you to install new exterior operating instruction placards for the exit doors. The proposed AD is the result of Raytheon improving the visibility and understandability of the door operating instruction placards. This was done as a result of difficulty opening the emergency exits of a similar type design airplane. The actions specified by the proposed AD are intended to assure that clear and complete operating instructions are visible for opening the exit doors. If not visible or understandable, this could result in the inability to open the exit door during an emergency situation.

DATES:

The Federal Aviation Administration (FAA) must receive any comments on this proposed rule on or before March 12, 2002.

ADDRESSES:

Submit comments to FAA, Central Region, Office of the Regional Counsel, Attention: Rules Docket No. 2001-CE-32-AD, 901 Locust, Room 506, Kansas City, Missouri 64106. You may view any comments at this location between 8 a.m. and 4 p.m., Monday through Friday, except Federal holidays.

You may get service information that applies to this proposed AD from Raytheon Aircraft Company, P.O. Box 85, Wichita, Kansas 67201-0085; telephone: (800) 429-5372 or (316) 676-3140. You may also view this information at the Rules Docket at the address above.

You may view all comments we receive before and after the closing date of the rule in the Rules Docket. We will file a report in the Rules Docket that summarizes each contact we have with the public that concerns the substantive parts of this proposed AD.

How can I be sure FAA receives my comment? If you want FAA to acknowledge the receipt of your comments, you must include a self-addressed, stamped postcard. On the postcard, write “Comments to Docket No. 2001-CE-32-AD.” We will date stamp and mail the postcard back to you.

Discussion

What events have caused this proposed AD? The FAA believes that the instructions for opening the exit doors are either not visible or not easy to understand on Raytheon Model 58P, 60, A60, B60, and 65-88 airplanes. This is based on an accident that resulted in the issuance of AD 97-04-02. AD 97-04-02 was later superseded by AD 98-21-20 to incorporate more visible and understandable instructions.

What are the consequences if the condition is not corrected? If the exterior door operating instruction placards are not visible or understandable, this could result in the inability to open the exit doors during an emergency situation.

Is there service information that applies to this subject? Raytheon has issued Mandatory Service Bulletin SB 11-3404, Issued: June, 2001.

What are the provisions of this service information? The service bulletin includes procedures for installing new exterior placards with improved operating instructions for the exit doors on the affected airplanes.

The FAA's Determination and an Explanation of the Provisions 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 on other Raytheon Model 58P, 60, A60, B60, and 65-88 airplanes of the same type design;

—The actions specified in the previously-referenced service information should be accomplished on the affected airplanes; and

—AD action should be taken in order to correct this unsafe condition.

What would this proposed AD require? This proposed AD would require you to install new exterior operating instruction placards for the exit doors.

Cost Impact

How many airplanes would this proposed AD impact? We estimate that this proposed AD affects 850 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 accomplish the proposed modification:

Labor costParts costTotal cost per airplaneTotal cost on U.S. operators
2 workhours X $60 per hour = $120$40$160$136,000

The manufacturer will provide warranty credit for parts to the extent noted under MATERIAL INFORMATION in Raytheon Mandatory Service Bulletin SB 11-3404, Issued: June, 2001.

Compliance Time of This Proposed AD

What would be the compliance time of this proposed AD? The compliance time of this proposed AD is “within the next 100 hours time-in-service (TIS) after the effective date of this AD or within the next 12 calendar months after the effective date of this AD, whichever occurs first”.

Why is the compliance time of this proposed AD presented in both hours TIS and calendar time? The unsafe condition on these airplanes is not a result of the number of times the airplane is operated. Airplane operation varies among operators. For example, one operator may operate the airplane 50 hours TIS in 3 months while it may take another operator 12 months or more to accumulate 50 hours TIS. For this reason, the FAA has determined that the compliance time of the proposed AD should be specified in both hours time-in-service (TIS) and calendar time in order to assure this condition is not allowed to go uncorrected over time.

Regulatory Impact

Would this proposed AD impact various entities? The regulations proposed herein would 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. Therefore, it is determined that this proposed rule would not have federalism implications under Executive Order 13132.

Would this proposed AD involve a significant rule or regulatory action? For the reasons discussed above, I certify that this proposed action (1) is not a “significant regulatory action” under Executive Order 12866; (2) is not a “significant rule” under DOT Regulatory Policies and Procedures (44 FR 11034, February 26, 1979); and (3) if promulgated, 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. A copy of the draft regulatory evaluation prepared for this action has been placed in the Rules Docket. A copy of it may be obtained by contacting the Rules Docket at the location provided under the caption ADDRESSES. Start Printed Page 1672
