AGENCY: Federal Aviation 

Administration (FAA), Department of 

Transportation (DOT). 

ACTION: Final rule; request for 

comments. 

SUMMARY: This amendment adopts a 

new airworthiness directive (AD) for the 

Schweizer Model 269D helicopters. This 

action requires installing a Scroll 

Housing Blade Containment Shielding 

Kit on each helicopter. This amendment 

is prompted by 21 reports of the blades 

of the oil cooler impeller separating, one 

of which punctured the engine and 

transmission oil cooler resulting in loss 

of engine oil pressure. The actions 

specified in this AD are intended to 

protect the oil cooler from uncontained 

oil cooler impeller blades that could 

damage the oil cooler and result in loss 

of engine and transmission oil pressure, 

and subsequent loss of control of the 

helicopter. 

DATES: Effective August 20, 2010.

SUPPLEMENTARY INFORMATION: This 

amendment adopts a new AD for the 

Schweizer Model 269D helicopters. This 

action requires installing a certain Scroll 

Housing Blade Containment Shielding 

Kit on each helicopter. This amendment 

is prompted by 21 reports of the blades 

of the oil cooler impeller separating and 

damaging the oil cooler. One failure 

resulted in an emergency landing when 

the crew experienced vibration and loss 

of oil pressure. Further investigation 

revealed that a portion of a fan impeller 

blade damaged the oil cooler resulting 

in a loss of oil. This condition, if not 

corrected, could result in loss of engine 

and transmission oil pressure and 

subsequent loss of control of the 

helicopter. 

We have reviewed Schweizer Service 

Bulletin No. DB–031, dated September 

1, 2009 (SB), which specifies installing 

a Scroll Housing Blade Containment 

Shielding Kit, part number (P/N) SA– 

269DK–048 on each Model 269D 

helicopter. The manufacturer developed 

the containment kit after a recent 

incident in which separation of a blade 

due to fatigue cracks at the root of the 

blade resulted in damage to the oil 

cooler and loss of engine oil pressure. 

The SB states that the containment kit 

will prevent the escape of any separated 

impeller blades from the scroll assembly 

and relieve the operator of daily and 25- 

hour time-in-service (TIS) inspections. 

The SB also states that future 

inspections of the cooling impeller will 

be done at 100-hour TIS intervals per 

the maintenance manual. 

This unsafe condition is likely to exist 

or develop on other helicopters of the 

same type design. Therefore, this AD is 

being issued to prevent failure of the oil 

cooler, loss of engine and transmission 


wwoods2 on DSK1DXX6B1PROD with RULES_PART 1
47198 Federal Register / Vol. 75, No. 150 / Thursday, August 5, 2010 / Rules and Regulations 

oil pressure, and subsequent loss of 

control of the helicopter. This AD 

requires installing a Scroll Housing 

Blade Containment Shielding Kit, P/N 

SA–269DK–048, on each helicopter. 

The short compliance time involved 

is required because the previously 

described critical unsafe condition can 

adversely affect the controllability and 

structural integrity of the helicopter. 

Therefore, installing an SA–269DK–048 

Scroll Housing Blade Containment 

Shielding Kit on each helicopter is 

required within 25 hours TIS, and this 

AD must be issued immediately. 

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. 

We estimate that this AD will affect 

21 helicopters, and removing the scroll 

assembly and installing the containment 

kit will take about 3 work hours at an 

average labor rate of $85 per work hour. 

Required parts will cost about $288 per 

helicopter. Based on these figures, we 

estimate the total cost impact of the AD 

on U.S. operators to be $11,403. 

Comments Invited 

This AD is a final rule that involves 

requirements that affect flight safety and 

was not preceded by notice and an 

opportunity for public comment; 

however, we invite you to submit any 

written data, views, or arguments 

regarding this AD. Send your comments 

to an address listed under ADDRESSES. 

Include ‘‘Docket No. FAA–2010–0758; 

Directorate Identifier 2010–SW–004– 

AD’’ at the beginning of your comments. 

We specifically invite comments on the 

overall regulatory, economic, 

environmental, and energy aspects of 

the AD. We will consider all comments 

received by the closing date and may 

amend the AD in light of those 

comments. 

We will post all comments we 

receive, without change, to http:// 

www.regulations.gov, including any 

personal information you provide. We 

will also post a report summarizing each 

substantive verbal contact with FAA 

personnel concerning this AD. Using the 

search function of our docket web site, 

you can find and read the comments to 

any of our dockets, including the name 

of the individual who sent the 

comment. You may review the DOT’s 

complete Privacy Act Statement in the 

Federal Register published on April 11, 

2000 (65 FR 19477–78). 

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 the regulation: 

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 an economic evaluation 

of the estimated costs to comply with 

this AD. See the AD docket to examine 

the economic evaluation. 

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 rulemaking 

action.
