AGENCY:

Federal Aviation Administration, DOT.

ACTION:

Final rule; request for comments.

SUMMARY:

This amendment adopts a new airworthiness directive (AD) that is applicable to all Raytheon Model Beech 400, 400A, and 400T series airplanes, Model Mitsubishi MU-300 airplanes, and Model Beech MU-300-10 airplanes. This action requires revising the Emergency Procedures Section of the Airplane Flight Manual to ensure the flightcrew is advised of in-flight procedures in the event of loss of airspeed indication. Such loss of airspeed indication and the resulting adverse effects on certain connecting systems could result in reduced controllability of the airplane.

DATES:

Effective December 11, 2001.

The incorporation by reference of certain publications listed in the regulations is approved by the Director of the Federal Register as of December 11, 2001.

Comments for inclusion in the Rules Docket must be received on or before February 4, 2002.

ADDRESSES:

Submit comments in triplicate to the Federal Aviation Administration (FAA), Transport Airplane Directorate, ANM-114, Attention: Rules Docket No. 2001-NM-347-AD, 1601 Lind Avenue, SW., Renton, Washington 98055-4056. Comments may be inspected at this location between 9 a.m. and 3 p.m., Monday through Friday, except Federal holidays. Comments may be submitted via fax to (425) 227-1232. Comments may also be sent via the Internet using the following address: 9-anm-iarcomment@faa.gov.

End Further Info End Preamble Start Supplemental Information

SUPPLEMENTARY INFORMATION:

The FAA has received several reports of loss of the pilot's and/or the co-pilot's Indicated Airspeed (IAS) display on certain Raytheon Model Beech 400A series airplanes. Such loss of IAS display may lead to loss of the altitude displays and up to 10 degrees of pitch error in the pilot's and/or co-pilot's attitude display. Loss of the Indicated Airspeed (IAS) display can also adversely affect the display for altitude and attitude (Attitude/Heading/Reference System (AHRS)), and can result in uncommanded autopilot or yaw damper disengagement. The reported incidents occurred between 38,000 and 41,000 feet of altitude while the airplanes were in cruise or during initial descent. In the reported incidents, the altitude indication returned to normal at an undetermined point in the descent, and the airplanes landed without further incident. Investigation of those reports indicates that the cause of the loss of airspeed indication display may be due to water freezing in the pitot systems.

Loss of airspeed indication and the resulting adverse effects on certain connecting systems could result in reduced controllability of the airplane.

Similar Models

The pitot systems installation on Raytheon Model Beech 400, and 400T series airplanes, Model Mitsubishi MU-300 airplanes, and Model Beech MU-300-10 airplanes are identical to those installed on the affected Model Beech 400A series airplanes. Therefore, all of these models may be subject to the same unsafe condition.

The FAA has reviewed and approved the following Raytheon Temporary Changes to the FAA-approved Airplane Flight Manual:

  • Beechjet 400T Temporary Change, P/N 132-590002-5TC3, dated November 12, 2001;

The documents specified above describe certain in-flight procedures in the event of loss of airspeed indication for the various models specified.

Explanation of the Requirements of the Rule

Since an unsafe condition has been identified that is likely to exist or develop on other airplanes of the same type design, this AD is being issued to ensure the flightcrew is advised of in-flight procedures in the event of loss of airspeed indication. Such loss of airspeed indication and the resulting adverse effects of certain connecting systems could result in reduced controllability of the airplane. This AD requires accomplishment of the actions specified in the Temporary AFM's described previously, or insertion of this AD into the Airplane Flight Manual (AFM).

Interim Action

This is considered to be interim action until final action is identified, at which time the FAA may consider further rulemaking.

Determination of Rule's Effective Date

Since a situation exists that requires the immediate adoption of this regulation, it is found that notice and opportunity for prior public comment hereon are impracticable, and that good cause exists for making this amendment effective in less than 30 days.

Comments Invited

Although this action is in the form of a final rule that involves requirements affecting flight safety and, thus, was not preceded by notice and an opportunity for public comment, comments are invited on this rule. Interested persons are invited to comment on this rule by submitting such written data, views, or arguments as they may desire. Communications shall identify the Rules Docket number and be submitted in triplicate to the address specified under the caption ADDRESSES. All communications received on or before the closing date for comments will be considered, and this rule may be amended in light of the comments received. Factual information that supports the commenter's ideas and suggestions is extremely helpful in evaluating the effectiveness of the AD action and determining whether additional rulemaking action would be needed.

Submit comments using the following format:

  • Organize comments issue-by-issue. For example, discuss a request to change the compliance time and a request to change the service bulletin reference as two separate issues.
  • For each issue, state what specific change to the AD is being requested.
  • Include justification (e.g., reasons or data) for each request.

Comments are specifically invited on the overall regulatory, economic, environmental, and energy aspects of the rule that might suggest a need to modify the rule. All comments submitted will be available, both before and after the closing date for comments, in the Rules Docket for examination by interested persons. A report that summarizes each FAA-public contact concerned with the substance of this AD will be filed in the Rules Docket.

Commenters wishing the FAA to acknowledge receipt of their comments submitted in response to this rule must submit a self-addressed, stamped postcard on which the following statement is made: “Comments to Docket Number 2001-NM-347-AD.” The postcard will be date stamped and returned to the commenter.

Regulatory Impact

The regulations adopted herein 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. Therefore, it is determined that this final rule does not have federalism implications under Executive Order 13132.

The FAA has determined that this regulation is an emergency regulation that must be issued immediately to correct an unsafe condition in aircraft, and that it is not a “significant regulatory action” under Executive Order 12866. It has been determined further that this action involves an emergency regulation under DOT Regulatory Policies and Procedures (44 FR 11034, February 26, 1979). If it is determined that this emergency regulation otherwise would be significant under DOT Regulatory Policies and Procedures, a final regulatory evaluation will be prepared and placed in the Rules Docket. A copy of it, if filed, may be obtained from the Rules Docket at the location provided under the caption ADDRESSES.

“Emergency Procedures (400 & MU-300)

Loss of Airspeed

Note:

If the pilot's and/or copilot's airspeed(s) are noted to be decreasing toward zero, refer to the AOA indicator for airspeed control and land at the nearest suitable airport.

1. Autopilot—Disconnect

2. Airspeed—Slow to and Maintain 0.2 AOA

3. Thrust—As Required Start Printed Page 63309

4. Speed Brakes—As Required (Slow to 0.25 AOA with speed brakes extended)

Note:

An AOA of 0.2 (0.25 with speed brakes extended) will yield an airspeed of about 210 knots. Use pitch attitude as the primary reference. Make small changes in pitch and wait for the AOA to stabilize.

When Ready for Descent

5. Seat Belts/Shoulder Harnesses—Fastened

Note:

If the pilot's, or copilot's and standby, or all three airspeed(s) are noted to be decreasing toward zero, refer to the standby attitude indicator, standby altimeter, standby heading and the AOA indicator for aircraft control and land at the nearest suitable airport. On PFD equipped airplanes, the pilot's and copilots altimeters, attitude displays and heading displays may be unreliable and the autopilot may disconnect. This may be accompanied by amber boxed A/S, ALT, ATT and/or HDG comparator flags. The comparator flags may be followed by red FAIL flags and removal of airspeed and altitude tapes and attitude/heading displays.
