Discussion

During routine maintenance on a de Havilland Model DH 82 airplane, it was found that the lateral fuselage tie rod at the aft position had sheared at its location with the spar attachment fitting. Investigation revealed that the failure was a result of fatigue cracking in the thread root. In addition, the forward tie rod (which had not fractured) was distorted and found to have been manufactured from material of incorrect specification with a lower tensile strength.

During our review of the abovereferenced cracking and the related mandatory service information, we determined that the life limit on the lateral fuselage tie rods is not currently addressed for airplanes on the U.S. registry. Mandatory service information is required for airplanes on the registry in certain other countries, but in the United States an AD must be issued to require the actions of a service bulletin for all airplanes.

De Havilland Model DH 82A airplanes (commonly referred to as Tiger Moths) are type certificated under two type certificates. TCDS A5PC, currently held by Harry E. Williams, is for airplanes built in Australia, and TCDS A8EU, currently held by Cliff Robertson, c/o Gadbois Business Management, is for airplanes built in the United Kingdom. This type certification approval was not by validation, but by an acceptance process; as such, the U.S. type certificate holders are not the manufacturers of the airplanes and the original manufacturers (de Havilland and its licensees) are not type certificate holders.

De Havilland Support Ltd (DHSL) holds the type certificate responsibility for de Havilland Model DH 82A airplanes (the type design for TCDS A8EU) in the United Kingdom.

DHSL is custodian of the airframe design data, manufacturing drawings, and repair schemes still in existence for de Havilland Model DH 82A Tiger Moth series airplanes only. In 2012, DHSL entered into a CAA Type Responsibility Agreement (TRA) so that the airplane remains eligible, if required, for an ICAO-compliant Certificate of Airworthiness to facilitate training and pleasure flying.

Similarly, Air Stratus Ltd holds the type certificate responsibility for de Havilland Model DH 83 airplanes (the type design for TCDS 2–439) in the United Kingdom.

This condition, if not corrected, could result in structural failure of the attachment of the wing to the fuselage. We are issuing this proposed AD to correct the unsafe condition on these products.

Relevant Service Information

We reviewed British Aerospace Military Aircraft and Aerostructures BAe Aircraft Bulletin for de Havilland Moth Aircraft, Document Type and Ref No Technical News Sheet CT (Moth) No 29, Issue 3, dated March 1, 1999, which was approved by the Civil Aviation Authority (CAA) for the United Kingdom to ensure the continued


### 54921 Federal Register / Vol. 79, No. 178 / Monday, September 15, 2014 / Proposed Rules

airworthiness of these airplanes in the United Kingdom. The service information introduces a life limit for the lateral fuselage tie rods and describes procedures for repetitively replacing the lateral fuselage tie rods and attaching nuts.

FAA’s Determination

We are proposing this AD because we evaluated all the relevant information and determined the unsafe condition described previously is likely to exist or develop in other products of the same type design.
Proposed AD Requirements

This proposed AD would require accomplishing the actions specified in the service information described previously. Costs of Compliance
We estimate that this proposed AD would affect 69 airplanes of U.S. registry.

We estimate the following costs to comply with this proposed AD:



### E STIMATED 

### C OSTS

Action Labor cost Parts cost Cost per product Cost on U.S. operators

Inspect the aircraft maintenance records to

determine the date of installation or dateof last replacement of the lateral fuselage tie rods and attaching nuts. 1 work-hour × $85 per hour = $85 Not applicable $85 $5,865

We estimate the following costs to the necessary replacements.



### E STIMATED 

### C OSTS

Action Labor cost Parts cost Cost per product

Replace lateral fuselage tie rods and attaching nuts ... 30 work-hours × $85 per hour = $2,550 ...................... $825 $3,375

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 proposed 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.
Regulatory Findings

We determined that this proposed AD would not have federalism implications under Executive Order 13132. This proposed AD would 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 this proposed 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),

(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. List of Subjects in 14 CFR Part 39

**AGENCY :**  Federal Aviation Administration (FAA), DOT. **ACTION :**  Notice of proposed rulemaking (NPRM).

**SUMMARY :**  We propose to supersede airworthiness directive (AD) 2001–13– 51 for Bell Model 206L–4, 407, and 427 helicopters. AD 2001–13–51 currently requires inspecting certain driveshafts for a crack, a loose bolt or nut, or red powder residue and replacing a driveshaft if there is a crack, a loose bolt or nut, or red powder residue. AD 2001– 13–51 also requires notifying the FAA within 10 days if a crack is found in the driveshaft. Since we issued AD 2001– 13–51, the Model 429 helicopter has been certificated, and the reporting requirement is no longer necessary. This proposed AD would retain the inspection requirement of AD 2001–13– 51, expand the applicability to include the Model 429 helicopter, and remove the reporting requirement. These proposed actions are intended to prevent failure of a driveshaft, loss of drive to the main rotor system, and a subsequent emergency landing.
