# SUPPLEMENTARY INFORMATION:

## Discussion

The European Aviation Safety Agency (EASA), which is the Technical Agent for the Member States of the European Community, has issued AD No. 2015-0023-E, dated February 18, 2015, (referred to after this as “the MCAI”), to correct an unsafe condition for Flugzeugwerke Altenrheim AG (FFA) Models AS 202/15 “BRAVO”, AS 202/18A “BRAVO”, and AS 202/18A4 “BRAVO” airplanes. The MCAI states:

Heavy corrosion was reportedly discovered on an AS 202 aeroplane, between the forward (FWD) windshield frame angle and the upper FWD stringer, left hand (LH) and right hand (RH). The corrosion was found underneath the removed windshield frame. Corrosion was not detected during a general visual inspection from below.

This condition, if not detected and corrected, could lead to failure of the FWD upper stringer, which reduces the structural integrity of the affected area.

To address this potential unsafe condition, Gomolzig Flugzeug- und Maschinenbau GmbH (GFM), acting on behalf of the TC holder, have issued Service Bulletin (SB) No. 2015-1 to provide inspection instructions.

For the reasons described above, this AD requires repetitive inspections of the upper FWD stringer (LH and RH) structure for signs of corrosion and, depending on the findings, the accomplishment of applicable corrective action(s).

This AD is considered to be an interim action and further AD action may follow.

                    You may examine the MCAI on the Internet at                     *http://www.regulations.gov*                     by searching for and locating Docket No. FAA-2015-0536.                

## Relevant Service Information Under 1 CFR Part 51

                    Gomolzig Flugzeug- und Maschinenbau GmbH has issued Service Bulletin GFM SB 2015-1, dated February 5, 2015. The actions described in this service information are intended to correct the unsafe condition identified in the MCAI. The Gomolzig Flugzeug- und Maschinenbau GmbH service bulletin describes procedures for inspecting the upper forward stringer (LH and RH) structure for signs of corrosion and making all necessary repairs. This service information is reasonably available; see                     **ADDRESSES**                     for ways to access this service information.                

## FAA's Determination and Requirements of the AD

This product has been approved by the aviation authority of another country, and is approved for operation in the United States. Pursuant to our bilateral agreement with this State of Design Authority, they have notified us of the unsafe condition described in the MCAI and service information referenced above. We are issuing this AD because we evaluated all information provided by the State of Design Authority and determined the unsafe condition exists and is likely to exist or develop on other products of the same type design.

This AD is considered an interim action. After issuing this AD, we may initiate further AD action to require a possible terminating action for the 12-month repetitive inspections.

## FAA's Determination of the Effective Date

                    An unsafe condition exists that requires the immediate adoption of this AD. The FAA has found that the risk to the flying public justifies waiving notice and comment prior to adoption of this rule because corrosion on the upper forward fuselage stringers could cause them to fail, which could result in reduced structural integrity of the windshield frame. Therefore, we determined that notice and opportunity for public comment before issuing this AD are impracticable and that good cause exists for making this amendment effective in fewer than 30 days.                          ( print page 13762)    

## Comments Invited

                    This AD is a final rule that involves requirements affecting flight safety, and we did not precede it by notice and opportunity for public comment. We invite you to send any written relevant data, views, or arguments about this AD. Send your comments to an address listed under the                     **ADDRESSES**                     section. Include “Docket No. FAA-2015-0536; Directorate Identifier 2015-CE-004-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 will affect 1 product of U.S. registry. We also estimate that it will take about 6 work-hours per product to comply with the basic requirements of this AD. The average labor rate is $85 per work-hour.

Based on these figures, we estimate the cost of the AD on U.S. operators to be $510.

In addition, we estimate that any necessary follow-on actions will take about 20 work-hours and require parts costing $1,000, for a cost of $2,700 per product. We have no way of determining at this time if the affected airplane may need these actions.

## 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.

## Regulatory Findings

We 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),

(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.

None.

## (c) Applicability

This AD applies to Flugzeugwerke Altenrheim AG (FFA) Models AS 202/15 “BRAVO”, AS 202/18A “BRAVO”, and AS 202/18A4 “BRAVO” airplanes, all serial numbers, certificated in any category.

## (d) Subject

Air Transport Association of America (ATA) Code 53: Fuselage.

## (e) Reason

This AD was prompted by a report of corrosion found on the upper forward windshield frame angle and the upper forward stringer. We are issuing this AD to detect and correct corrosion on the left-hand (LH) and the right-hand (RH) upper forward fuselage stringers. If not detected and corrected, this condition could lead to failure of the LH and/or the RH upper forward fuselage stringers, which could result in reduced structural integrity of the windshield frame.

## (f) Actions and Compliance

Unless already done, do the following actions.

(1) Before further flight after March 17, 2015 (the effective date of this AD) and thereafter at intervals not to exceed 12 months, do a detailed visual inspection of the LH and RH forward (FWD) upper stringer top side structure for corrosion and any signs of damage to the corrosion protection. Do the inspection following the Instructions section in Gomolzig Flugzeug- und Maschinenbau GmbH Service Bulletin GFM SB 2015-1, dated February 5, 2015.

(2) If corrosion or any signs of damage to the corrosion protection is found during any inspection required in paragraph (f)(1) of this AD, before further flight after the inspection where corrosion or signs of damage to the corrosion protection is found, remove the corrosion at the affected area following the Instructions section in Gomolzig Flugzeug- und Maschinenbau GmbH Service Bulletin GFM SB 2015-1, dated February 5, 2015.

(3) If corrosion is found during any inspection required in paragraph (f)(1) of this AD that exceeds the allowable limits specified in paragraph 1.f of the Instructions section in Gomolzig Flugzeug- und Maschinenbau GmbH Service Bulletin GFM SB 2015-1, dated February 5, 2015, before further flight after the inspection where corrosion is found that exceeds the allowable limits, contact Gomolzig Flugzeug- und Maschinenbau GmbH at the address specified in paragraph (i)(3) of this AD for an FAA-approved repair scheme and incorporate the repair.

(4) Within 30 days after doing the initial inspection required in paragraph (f)(1) of this AD, report the results, including findings of no corrosion, to Gomolzig Flugzeug- und Maschinenbau GmbH at the address specified in paragraph (i)(3) of this AD using page 5 of Gomolzig Flugzeug- und Maschinenbau GmbH Service Bulletin GFM SB 2015-1, dated February 5, 2015.
