Rule

Airworthiness Directives; Allied Ag Cat Productions, Inc. (Type Certificate No. 1A16 Formerly Held by Schweizer Aircraft Corp.) G-164 Series Airplanes

Action

Final Rule.

Summary

We are adopting a new airworthiness directive (AD) to supersede AD 82-07-04, which applies to certain Allied Ag Cat Productions, Inc. (Ag Cat) G-164 series airplanes. AD 82-07-04 currently requires you to modify the fuel shut-off valve control by installing a new stop-plate. Since we issued AD 82-07-04, we have determined the need to add airplane models and serial numbers that were not previously included in the Applicability section. Consequently, this AD retains the actions of AD 82-07-04 and adds airplane models and serial numbers to the Applicability section. We are issuing this AD to prevent turning the fuel shut-off valve clockwise past the “ON” position stop which, if not corrected, could allow the fuel valve to be rotated to an unplacarded “OFF” position. This condition could lead to reduced fuel flow and consequent loss of engine power.

Discussion Back to Top

On May 9, 2007, 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 Ag Cat G-164 series airplanes. This proposal was published in the Federal Register as a notice of proposed rulemaking (NPRM) on May 16, 2007 (72 FR 27489). The NPRM proposed to retain the actions of AD 82-07-04 and add airplane models and serial numbers to the applicability.

Comments Back to Top

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 Back to Top

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.

Differences Between This AD and the Service Information Back to Top

This AD affects additional models and serial numbers airplanes compared to the list in the applicability section of the service information. The requirements of this AD take precedence over the provisions in the service information.

Costs of Compliance Back to Top

We estimate that this AD affects 1,400 airplanes in the U.S. registry, including those airplanes affected by AD 82-07-04.

We estimate the following costs to do the modification:

Labor cost Parts cost Total cost per airplane Total cost on U.S. operators
2.5 work-hours × $80 per hour = $200 $500 $700 $980,000

We based our fleet cost estimate on all airplanes needing the modification. We have no way of knowing which airplanes already have modified the fuel shut-off control per AD 82-07-04. We also have no way of knowing how many airplanes have been retrofitted with the Gemini fuel shut-off valve part number 3/4-86-6-RT-6 (A3580-1) without incorporating AD 82-07-04.

The estimated total cost on U.S. operators includes the cumulative costs associated with those airplanes affected by AD 82-07-04 and those airplanes being added in this AD.

Authority for This Rulemaking Back to Top

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 Back to Top

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. Include “Docket No. FAA-2007-27860; Directorate Identifier 2007-CE-034-AD” in your request.

Adoption of the Amendment Back to Top

Accordingly, under the authority delegated to me by the Administrator, the Federal Aviation Administration amends part 39 of the Federal Aviation Regulations (14 CFR part 39) as follows:

PART 39—AIRWORTHINESS DIRECTIVES Back to Top

1.The authority citation for part 39 continues to read as follows:

Authority:

49 U.S.C. 106(g), 40113, 44701.

§ 39.13 [Amended]

2.The FAA amends § 39.13 by removing Airworthiness Directive (AD) 82-07-04, Amendment 39-4355, and adding the following new AD:

2007-17-02Allied Ag Cat Productions, Inc. (Type Certificate No. 1A16 formerly held by Schweizer Aircraft Corp.): Amendment 39-15160; Docket No. FAA-2007-27860; Directorate Identifier 2007-CE-034-AD.

Effective Date Back to Top

(a) This AD becomes effective on September 18, 2007.

Affected ADs Back to Top

(b) This AD supersedes AD 82-07-04, Amendment 39-4355.

Applicability Back to Top

(c) This AD applies to the following model and serial number airplanes that are certificated in any category and have Gemini fuel shut-off valve part number (P/N) 3/4-86-6-RT-6 (A3580-1) installed:

(1) Group 1 (maintains the actions from AD 82-07-04):

Model Serial Nos.
(i) G-164A 1726A through 1730A.
(ii) G-164B 335B through 659B.
(iii) G-164C 1C through 44C.
(iv) G-164D 1D through 22D.

(2) Group 2:

Model Serial Nos.
(i) G-164 All.
(ii) G-164A All except 1726A through 1730A.
(iii) G-164B and G-164B with 73″ wing gap All except 335B through 659B.
(iv) G-164B-15T All.
(v) G-164B-20T All.
(vi) G-164B-34T All.
(vii) G-164C All except 1C through 44C.
(iv) G-164D and G-164D with 73″ wing gap All except 1D through 22D.

Unsafe Condition Back to Top

(d) This AD results from our determination to add airplane models and serial numbers that were not previously included in the applicability. We are issuing this AD to prevent turning the fuel shut-off valve clockwise past the “ON” position which, if not corrected, could allow the fuel valve to be rotated to an unplacarded “OFF” position.

Compliance Back to Top

(e) To address this problem, you must do the following, unless already done:

Actions Compliance Procedures
(1) Modify the fuel shut-off valve control by installation of a new stop-plate, P/N A1552-71 (or FAA-approved equivalent) (i) For Group 1 Airplanes: Within the next 100 hours time-in-service (TIS) after April 6, 1982 (the effective date of AD 82-07-04) Follow Schweizer Aircraft Corp.
