Airworthiness Directives; CENTRAIR 

101 Series Gliders 

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Final rule. 

SUMMARY: The FAA adopts a new 

airworthiness directive (AD) for all 

CENTRAIR 101 series gliders. This AD 

requires you to make pen and ink 

changes to the Limitations Section of 

the glider maintenance manual to 

eliminate contradictory information 

concerning the structural life limit. This 

AD results from a review by FAA of the 

Limitations Section of the CENTRAIR 

Model 101AP glider maintenance 

manual that revealed conflicting 

information concerning the structural 

life limit. We are issuing this AD to 

assure that the published life limit is 

adhered to and to prevent structural 

failure of the glider once this life limit 

is reached. 

DATES: This AD becomes effective on 

January 3, 2006.

SUPPLEMENTARY INFORMATION: 

Discussion 

What events have caused this AD? A 

review by FAA of the Limitations 

Section of the CENTRAIR Model 101AP 

glider maintenance manual revealed 

conflicting information concerning the 

structural life limit. Page 5.1 of this 

manual specifies inspection criteria 

upon accumulating 3,000 hour time-inservice (TIS). However, page 5.01 of the 

manual identifies a structural life limit 

of 3,000-hour TIS. CENTRAIR has 

verified that all the 101 series gliders 

delivered to the United States have a 

3,000-hour life limit with no current 

extension. 

Cumulative fatigue damage and 

fatigue cracking damage would 

sufficiently reduce residual strength of 

the airframe and result in failure of the 

airframe. 

What is the potential impact if FAA 

took no action? If this situation is not 

corrected, the published life limit may 

not be adhered to and the structural 

integrity of the glider could be 

compromised. 

Has FAA taken any action to this 

point? 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 all 

CENTRAIR 101 series gliders. This 

proposal was published in the Federal 

Register as a notice of proposed 

rulemaking (NPRM) on August 22, 2005 

(70 FR 48918). The NPRM proposed to 

require you to make pen and ink 

changes to the Limitations Section of 

the glider maintenance manual to 

eliminate contradictory information 

concerning the structural life limit. 

Comments 

Was the public invited to comment? 

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 

What is FAA’s final determination on 

this issue? 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. 

Changes to 14 CFR Part 39—Effect on 

the AD 

How does the revision to 14 CFR part 

39 affect this AD? On July 10, 2002, the 

FAA published a new version of 14 CFR 

part 39 (67 FR 47997, July 22, 2002), 

which governs the FAA’s AD system. 

This regulation now includes material 

that relates to altered products, special 

flight permits, and alternative methods 

of compliance. This material previously 

was included in each individual AD. 

Since this material is included in 14 

CFR part 39, we will not include it in 

future AD actions. 

Costs of Compliance 

How many gliders does this AD 

impact? We estimate that this AD affects 

51 gliders in the U.S. registry. 

What is the cost impact of this AD on 

owners/operators of the affected gliders? 

We estimate the following costs to do 

this change of the maintenance manual: 

Labor cost Parts cost Total cost 

per glider 

Total cost on 

U.S. operators 

1 work hour × $65 = $65 .......................................................................................................... Not Applicable. $65 $3,315 

69896 Federal Register / Vol. 70, No. 222 / Friday, November 18, 2005 / Rules and Regulations 

Authority for This Rulemaking 

What authority does FAA have for 

issuing this rulemaking action? 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 

Will this AD impact various entities? 

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. 

Will this AD involve a significant rule 

or regulatory action? 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. 

Include ‘‘Docket No. FAA–2005–21951; 

Directorate Identifier 2005–CE–39–AD’’

in your request.

What Must I Do To Address This Problem? 

(e) To address this problem, you must do 

the following: 

Actions Compliance Procedures 

Using pen and ink, change Section 5.1 of the 

Limitations Section of the CENTRAIR Gliders 

CENTRAIR 101—101 P–101 A–101 AP 

Maintenance Manual under ‘‘General Inspection,’’ to read, ‘‘The general inspection should 

be executed every 5 years until the 3,000- 

hour time-in-service structural life limit is 

met.’’ The above change enforces the 3,000- 

hour structural life limit set out in page 5.01—

Life Limits of the maintenance manual.

Within the next 30 days after January 3, 2006 

(the effective date of this AD).

The owner/operator holding at least a private 

pilot certificate as authorized by section 

43.7 of the Federal Aviation Regulations 

(14 CFR 43.7) may modify the maintenance 

manual as specified in paragraph (e) of this 

AD. Make an entry into the aircraft records 

showing compliance with this portion of the 

AD following section 43.9 of the Federal 

Aviation Regulations (14 CFR 43.9).
