Airworthiness Directives; Empresa Brasileira de Aeronautica S.A. (EMBRAER) Model EMB-120 Series Airplanes
AGENCY: Federal Aviation Administration, DOT.
ACTION: Final rule; request for comments.
SUMMARY: This amendment supersedes an existing airworthiness directive (AD), applicable to all EMBRAER Model EMB-120 series airplanes, that currently requires revising the Airplane Flight Manual, installing a placard on the main instrument panel, and removing the ``LIGHT-HEAVY'' inflation switch of the leading edge deicing boots. This amendment continues to require those actions and adds requirements to install a low speed alarm for icing conditions, to revise the AFM, and to replace an existing placard with a placard that directs the flightcrew to activate the deicing boots whenever ice is detected by visual cues or ice detector illumination. This amendment is prompted by issuance of mandatory continuing airworthiness information by a foreign civil airworthiness authority. This action is intended to ensure that the flightcrew is provided with accurate indications of the severity of ice accretion, clear indication of unintentional airplane speed reductions in icing conditions, and appropriate procedures to prevent reduced controllability of the aircraft due to accretion of ice on the airplane.
DATES: Effective October 22, 2001.
The incorporation by reference of certain publications listed in the regulations is approved by the Director of the Federal Register as of October 22, 2001.

SUPPLEMENTARY INFORMATION: On June 20, 2001, the FAA issued AD 2001-13- 14, amendment 39-12295 (66 FR 34083, June 27, 2001), applicable to all EMBRAER Model EMB-120 series airplanes, to require revising the Airplane Flight Manual (AFM), installing a placard on the main instrument panel, and removing the ``LIGHT-HEAVY'' inflation switch of the leading edge deicing boots. That action was prompted by issuance of mandatory continuing airworthiness information by a foreign civil airworthiness authority. The actions required by that AD are intended to ensure that the flightcrew is provided with accurate indications of the severity of ice accretion and appropriate procedures and actions to prevent reduced controllability of the airplane due to accretion of ice on the airplane.
Actions Since Issuance of Previous Rule
Since the issuance of that AD, the Departmento de Aviacao Civil (DAC), which is the airworthiness authority for Brazil, has notified the FAA that an unsafe condition may exist on all EMBRAER Model EMB-120 series airplanes. The DAC advises that it has received reports of loss of control events occurring on EMBRAER Model EMB-120 series airplanes that were flying during icing conditions. The DAC advises that such events indicate that the flightcrews may not have correctly determined both the severity of the ice accretion and the need to take immediate action to prevent excessive loss of airspeed, especially when using the autopilot. This situation, if not corrected, could result in reduced controllability of the airplane due to accretion of ice on the airplane.
Issuance of Service Information
EMBRAER has issued Service Bulletin 120-30-0033, Change 01, dated September 6, 2001, that describes procedures for installing a low speed alarm on the glareshield panel, adding new electrical wires in the cockpit and in the electronic compartment, installing or replacing two placards, and reworking the pitot-static system between frames 3 and 4.
EMBRAER also issued Service Bulletin 120-30-0033, Change 02, dated September 14, 2001, which includes two new electrical diagrams, corrects the hook-up charts, and describes a check for correct installation of diodes.
EMBRAER has issued Service Bulletin 120-25-0258, Change 01, dated August 30, 2001, which describes procedures for installing a placard to instruct pilots to immediately activate the deicing boots and disengage the autopilot, whenever ice is detected by visual cues or ice detector illumination. The original issue of Service Bulletin 120-25-0258, dated May 14, 2001, was cited as a source of service information in AD 2001- 13-14. Change 01is identical in technical content to the original service bulletin, and merely specifies that a new placard has been developed for airplanes that have been modified per EMBRAER Service Bulletin 120-30-0033, and contains procedures for installing the new placard.
The DAC classified these service bulletins as mandatory and issued Brazilian airworthiness directive 2001-05-02R1, effective September 30, 2001, in order to assure the continued airworthiness of these airplanes in Brazil.

FAA's Conclusions
This airplane model is manufactured in Brazil and is type certificated for operation in the United States under the provisions of section 21.29 of the Federal Aviation Regulations (14 CFR 21.29) and the applicable bilateral airworthiness agreement. Pursuant to this bilateral airworthiness agreement, the DAC has kept the FAA informed of the situation described above. The FAA has examined the findings of the DAC, reviewed all available information, and determined that AD action is necessary for products of this type design that are certificated for operation in the United States.
Explanation of Requirements of Rule
Since an unsafe condition has been identified that is likely to exist or develop on other airplanes of the same type design registered in the United States, this AD supersedes AD 2001-13-14 to continue to require revising the AFM, installing a placard on the main instrument panel, and removing the ``LIGHT-HEAVY'' inflation switch of the leading edge deicing boots. This AD will also require installing a low speed alarm for icing conditions, revising the AFM, and replacing an existing placard with a placard that directs the flightcrew to activate the deicing boots whenever ice is detected by visual cues or ice detector illumination.
Differences Between This AD and the Brazilian AD
This AD differs from the Brazilian AD in the following ways:
-
This AD is more specific as to when to disconnect the autopilot.
-
This AD includes instructions to remove the current information contained in the Normal Procedures Section advising the flightcrew to select either HEAVY or LIGHT mode.
-
This AD adds a WARNING to the Normal Procedures section to exit icing conditions if the flightcrew detects large or frequent changes in trim or excessive performance degradation.
-
This AD includes additional AFM instructions regarding abnormal operations with the icing low speed alarm activated.
-
This AD also includes dispatch relief regarding certain Master Minimum Equipment List items for the ice detection system and the new icing low speed alarm system.
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 filedin 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-298-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.
