SUMMARY: We are adopting a new 

airworthiness directive (AD) for the 

Kaman Model K–1200 helicopters. This 

AD requires revising the Limitations 

section of the Instructions for Continued 

Airworthiness (ICA) by establishing a 

life limit of 8,000 hours time-in-service 

(TIS) for each main rotor blade (blade) 

set. Also, this AD requires removing 

each blade set from service if it has 

accumulated 8,000 or more hours timein-service (TIS). This AD also requires 

replacing certain blade sets with 

airworthy blade sets at specified 

intervals based on the blade set serial 

number (S/N). This AD was prompted 

by an accident and the subsequent 

discovery of cracks in multiple blade 

spars. We are issuing this AD to prevent 

blade failure and subsequent loss of 

control of the helicopter.

SUPPLEMENTARY INFORMATION: 

Discussion 

We are adopting a new AD for the 

Kaman Model K–1200 helicopters that 

requires revising the Airworthiness 

Limitations section of the ICA by 

establishing a life limit of 8,000 hours 

TIS for each blade set. Previously, these 

blades sets did not have an established 

retirement life but had specified 

overhaul intervals. This AD also 

requires removing each blade set with 

8,000 or more hours TIS from service. 

Also, this AD requires replacing certain 

blade sets with airworthy blade sets at 

specified intervals based on the blade 

set S/N. This AD was prompted by an 

accident and the subsequent discovery 

of cracks in multiple blade spars. This 

condition, if not corrected, could result 

in a cracked spar, failure of a blade, and 

subsequent loss of control of the 

helicopter. 

Relevant Service Information 

We reviewed Kaman Service Bulletin 

No. 131, Rotor Blade Service Life 

Reduction, dated August 11, 2010 (SB). 

The SB specifies establishing ‘‘a service 

life of K–1200 rotor blade spar 

bondment (K911004) to 8,000 hours 

time since new (TSN)’’ and removing all 

blade sets with over 8,000 hours TIS. 

FAA’s Determination 

We are issuing this AD because we 

evaluated all the relevant information 

and determined the unsafe condition 

described previously is likely to exist or 

develop in other helicopters of this 

same type design.

Federal Register / Vol. 75, No. 244 / Tuesday, December 21, 2010 / Rules and Regulations 79951 

AD Requirements 

This AD requires, before further flight, 

revising the Airworthiness Limitations 

section of the ICA by establishing a life 

limit of 8,000 hours TIS for each 

affected blade set. This AD requires 

replacing the specified blade sets with 

airworthy blade sets at various intervals 

depending on TIS. Based on the 

individualized data from those 

operators with the affected serialnumbered blade sets, those serial 

numbered blade sets with the highest 

hours TIS are required to be replaced 

sooner than those with less hours TIS. 

Differences Between the AD and the 

Service Information 

This AD requires, before further flight, 

revising the Airworthiness Limitations 

section of the ICA to establish a life 

limit of 8,000 hours TIS for each blade 

set. Also, this AD requires replacing 

certain blade sets with airworthy blade 

sets at specified intervals based on the 

blade S/N. 

FAA’s Justification and Determination 

of the Effective Date 

An unsafe condition exists that 

requires the immediate adoption of this 

AD. The FAA finds that the risk to the 

flying public justifies waiving notice 

and comment prior to adopting this rule 

because cracks have been found in the 

blade spars during an investigation in 

response to an accident. Due to the 

number of hours TIS of the fleet, some 

of the blade sets may have exceeded 

8,000 hours TIS and the blade sets may 

be required to be replaced before further 

flight. Therefore, we find that notice and 

opportunity for prior public comment 

are impracticable and that good cause 

exists for making this amendment 

effective in less than 30 days. 

Comments Invited 

This AD is a final rule that involves 

requirements affecting flight safety and 

was not preceded by notice and an 

opportunity for public comment. 

However, we invite you to send any 

written data, views, or arguments about 

this AD. Send your comments to an 

address listed under the ADDRESSES

section. Include the docket number 

FAA–2010–1253 and Directorate 

Identifier 2010–SW–084–AD at the 

beginning of your comments. We 

specifically invite comments on the 

overall regulatory, economic, 

environmental, and energy aspects of 

this AD. We will consider all comments 

received by the closing date and may 

amend this AD because 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 we receive 

about this AD. 

Costs of Compliance 

We estimate that this AD affects 14 

helicopters of U.S. registry. The Kaman 

Model K–1200 helicopter is unique in 

that each helicopter has 2 sets of 2 

blades, a total of 4 blades per helicopter. 

Some helicopters only require one set of 

blades to be replaced. 

We estimate the following costs to 

comply with this AD: 

ESTIMATED COSTS

Action Labor cost Parts cost Cost per 

helicopter Cost on U.S. operators 

Replace blade set (2 

blades).

4 work-hours × $85 per 

hour = $340 per blade 

set.

$198,751 per blade set ..... $199,091 per blade set ..... $1,393,637, assuming 7 

blade sets are replaced. 

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 

helicopters identified in this rulemaking 

action. 

Regulatory Findings 

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 

DOT Regulatory Policies and Procedures 

(44 FR 11034, February 26, 1979), 

(3) Will not affect intrastate aviation 

in Alaska, and 

(4) 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.

ACTION: Final rule. 

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: 

During maintenance on one aircraft, it was 

discovered that the overpressure capsules 

were broken on both pressurization valves. 

Failure of the pressurization control 

regulating valve (overpressure capsule) will 

affect the aircraft’s overpressure protection 

* * *. 

* * * * * 

The unsafe condition is 

overpressurization, which can result in 

injury to the occupants and possible 

structural failure leading to loss of 

control of the airplane. We are issuing 

this AD to require actions to correct the 

unsafe condition on these products. 

DATES: This AD becomes effective 

January 25, 2011.

SUPPLEMENTARY INFORMATION: 

Discussion 

We issued a supplemental notice of 

proposed rulemaking (NPRM) to amend 

14 CFR part 39 to include an AD that 

would apply to the specified products. 

That supplemental NPRM was 

published in the Federal Register on 

July 27, 2010 (75 FR 43878). That 

supplemental NPRM proposed to 

correct an unsafe condition for the 

specified products. The MCAI states: 

During maintenance on one aircraft, it was 

discovered that the overpressure capsules 

were broken on both pressurization valves. 

Failure of the pressurization control 

regulating valve (overpressure capsule) will 

affect the aircraft’s overpressure protection, 

possibly resulting in a structural failure in 

case of combination with another 

pressurization system failure. Consequently, 

Dassault Aviation has developed a repetitive 

check of this outflow valve capsule, which 

has already been introduced into the 

Maintenance of Components section (chapter 

5–20) of the relevant Aircraft Maintenance 

Manuals (AMMs). 

For the reason described above, this EASA 

[European Aviation Safety Agency] 

Airworthiness Directive (AD) requires a 

repetitive check of the outflow valve 

overpressure capsule, as it will also be 

introduced into the Airworthiness 

Limitations section (chapter 5–40) of the 

respective AMMs. 

The unsafe condition is 

overpressurization, which can result in 

injury to the occupants and possible 

structural failure leading to loss of 

control of the airplane. Required actions 

include repetitive inspections for 

overpressure tightness on both 

regulating valves, and replacing the 

affected valve with a serviceable unit if 

necessary. You may obtain further 

information by examining the MCAI in 

the AD docket. 

Comments 

We gave the public the opportunity to 

participate in developing this AD. We 

considered the comment received. 

Request for Certain Airplanes To Be 

Included in the Time Extension 

Dassault Aviation requested that we 

revise the supplemental NPRM to 

extend the time interval for Model 

Mystere-Falcon 50 airplanes, for the 

overpressure tightness check that was 

specified in the supplemental NPRM. 

The extension of the time interval 

specified in the supplemental NPRM 

was from 1,630 flight hours to 1,640 

flight hours for other models. 

We agree to extend the time interval 

for Model Mystere-Falcon 50 airplanes
