**ACTION** 

### : Final rule.

**SUMMARY** 

### : We are adopting a new airworthiness directive (AD) for certain Hawker Beechcraft Corporation Model 390 airplanes. This AD requires you to inspect for installation of certain serial number (S/N) starter generators and replace the starter generator if one with an affected serial number is found. This AD results from reports that starter generators with deficient armature insulating materials may have been installed on certain airplanes. We are issuing this AD to detect and replace starter generators with defective armature insulating materials. This condition could result in the loss of operation of one or both starter generators with consequent loss of all non battery electrical power.

Discussion

On May 14, 2010, we issued a proposal to amend part 39 of the Federal Aviation Regulations (14 CFR part 39) to include an AD that would apply to certain serial number starter generators where deficient armature insulating materials may have been installed on Hawker Beechcraft Corporation Model 390 airplanes. This proposal was published in the Federal Register as a notice of proposed rulemaking (NPRM) on May 21, 2010 (FR 75 28506). The NPRM proposed to detect and replace starter generators with deficient armature insulating materials. This condition could result in the loss of operation of one or both starter


## 52236 Federal Register / Vol. 75, No. 164 / Wednesday, August 25, 2010 / Rules and Regulations

generators with consequent loss of all non battery electrical power.

Comments

We provided the public the opportunity to participate in developing this AD. We received no comments on the proposal or on the determination of the cost to the public. Conclusion We have carefully reviewed the available data and determined that air safety and the public interest require adopting the AD as proposed except for minor editorial corrections. We have determined that these minor corrections:

• are consistent with the intent that was proposed in the NPRM for correcting the unsafe condition; and • do not add any additional burden upon the public than was already proposed in the NPRM.
Costs of Compliance

We estimate that this AD affects 213 airplanes in the U.S. registry.

We estimate the following costs to do the inspection:

Labor cost Parts cost Total cost per airplane Total cost on U.S. operators

.5 work-hour × $85 per hour = $42.50 ........................................ Not applicable .................................................... .... $42.50 $9,052.50



### We estimate the following costs to do any necessary replacements that would be required based on the results of the inspection. We have no way of determining the number of airplanes that may need this replacement:

Labor cost Parts cost Total cost per airplane

10 work-hours (5 work-hours per side) × $85 per hour = $850 .............. $4,069 per side = $8,138 ................................................. $8,988



### Authority for This Rulemaking

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

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.

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 other information as included in the Regulatory Evaluation) 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**

**ACTION** 

### : Final rule; request for
comments.

**SUMMARY** 

### : We are adopting a new airworthiness directive (AD) for the products listed above. This AD results from mandatory continuing airworthiness information (MCAI) originated by an aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI describes the unsafe condition as:

It has been found the possibility of right hand (RH) engine compressor stall after the Auxiliary Power Unit (APU) becomes the active bleed source for the left side. The most critical condition identified is: —Both engines close to idle ( e.g.: descent

phase); and —APU running; and —APU bleed button pushed in.

In this condition, if the left hand (LH) engine fails, the APU bleed valve and the crossbleed valve may be both in the open position for a few seconds, [which] may lead to a backpressure in RH engine depending on APU bleed pressure. Such backpressure may cause an RH engine compressor stall, culminating in a dual engine failure.


### * * * * * This AD requires actions that are intended to address the unsafe condition described in the MCAI.

**DATES** 

### : This AD becomes effective September 9, 2010.

The Director of the Federal Register approved the incorporation by reference of a certain document listed in the AD as of September 9, 2010.

We must receive comments on this AD by October 12, 2010.

**SUPPLEMENTARY INFORMATION** 

### : Discussion The Age ˆ ncia Nacional de Aviac

 ̧ a  ̃ o Civil (ANAC), which is the aviation authority for Brazil, has issued Brazilian Airworthiness Directives 2010–07–02 and 2010–07–03, both effective July 31, 2010 (referred to after this as ‘‘ the MCAI ’’ ), to correct an unsafe condition for the specified products. The MCAI
states:

It has been found the possibility of right hand (RH) engine compressor stall after the Auxiliary Power Unit (APU) becomes the active bleed source for the left side.

The most critical condition identified is: —Both engines close to idle ( e.g.: descent

phase); and —APU running; and —APU bleed button pushed in.

In this condition, if the left hand (LH) engine fails, the APU bleed valve and the crossbleed valve may be both in the open position for a few seconds, [which] may lead to a backpressure in RH engine depending on APU bleed pressure. Such backpressure may cause an RH engine compressor stall, culminating in a dual engine failure.


### * * * * * The corrective action includes revising the Limitations sections of the applicable airplane flight manual to inform operators about the possibility of having an engine stall after the APU becomes the active bleed source for the left side and to specify the condition where APU bleed must not be used. You may obtain further information by examining the MCAI in the AD docket.

Interim Action

We consider this AD interim action. If final action is later identified, we might consider further rulemaking then.

Relevant Service Information

EMBRAER has issued Operational Bulletin 170–001/09, Revision 1, dated February 10, 2010, applicable to both Model ERJ 170 and ERJ 190 airplanes. The actions described in this service information are intended to correct the unsafe condition identified in the MCAI. FAA’s Determination and Requirements of This AD

This product has been approved by the aviation authority of another country, and is approved for operation in the United States. Pursuant to our bilateral agreement with the State of Design Authority, we have been notified of the unsafe condition described in the MCAI and service information referenced above. We are issuing this AD because we evaluated all pertinent information and determined the unsafe condition exists and is likely to exist or
