**Airworthiness Directives; Bombardier, Inc. Airplanes** 

**AGENCY :**  Federal Aviation Administration (FAA), DOT.

**ACTION :**  Notice of proposed rulemaking (NPRM).

**SUMMARY :**  We propose to adopt a new airworthiness directive (AD) for certain Bombardier, Inc. Model BD–700–1A10 and BD–700–1A11 airplanes. Thisproposed AD was prompted by inservice reports of passenger door tensator spring failures, and qualification testing that determined that non-conforming tensator springs could be susceptible to failure prior to reaching their safe-life limit. This proposed AD would require revising the maintenance or inspection program to incorporate certain temporary revisions, and replacing the passenger door tensator springs with new springs. We are proposing this AD to prevent tensator spring failure, resulting in the inability to open the main passenger door, which could impede evacuation in the event of an emergency.

**DATES :**  We must receive comments on this proposed AD by April 18, 2016.

Discussion

Transport Canada Civil Aviation (TCCA), which is the aviation authority for Canada, has issued Canadian Airworthiness Directive CF–2014–39,


### 11472 Federal Register / Vol. 81, No. 43 / Friday, March 4, 2016 / Proposed Rules

dated November 4, 2014 (referred to after this as the Mandatory Continuing Airworthiness Information, or ‘‘the MCAI’’), to correct an unsafe condition for certain Bombardier, Inc. Model BD– 700–1A10 and BD–700–1A11 airplanes. The MCAI states:

Following the issuance of [Canadian] AD CF–2010–14 [http://wwwapps3.tc.gc.ca/SafSec-Sur/2/cawis-swimn/awd-display-cs2101- wnd.asp?rand=&vMode=0&showPdf=False& ovid=CF

_CF–2010–14

_0], additional qualification testing of the passenger door tensator spring, Part Number (P/N) GS321– 0580–1, determined that the tensator springs could be susceptible to failure prior to reaching the life limit mandated by [Canadian] AD CF–2010–14.

In addition, there have been in-service reports of passenger door tensator spring failures. Investigation determined that the material used to manufacture the tensator springs [was] improperly heat treated.

The passenger door assembly is installed with four tensator springs that assist the dooractuator in opening and closing the door. Inservice experience has shown that a failed tensator spring could uncoil and foul up the rotating tensator spools, resulting in the inability to open the main passenger door. The inability to open the main passenger door could impede evacuation in the event of an emergency.

This [Canadian] AD mandates the revision to the approved maintenance schedule to reduce the repetitive discard task intervaland mandates the replacement of nonconforming tensator springs.

You may examine the MCAI in the AD docket on the Internet at http:// www.regulations.gov by searching for and locating Docket No. FAA–2016–
3989.

Related Service Information Under 1 CFR Part 51

We reviewed the following Bombardier, Inc. service information:

• Bombardier Global 5000 Service Bulletin 700–1A11–52–023, dated October 4, 2013.

• Bombardier Global Express/Global Express XRS Service Bulletin 700–52– 046, dated October 4, 2013.

• Temporary Revision (TR) 5–2–7, dated June 4, 2014, to Part 2, Section 5– 10–11, of Bombardier Global Express XRS BD–700 Time Limits/Maintenance Checks.

• TR 5–2–10, dated September 9, 2014, to Part 2, Section 5–10–11, of Bombardier Global 6000 GL 6000 Time Limits/Maintenance Checks.

• TR 5–2–13, dated June 4, 2014, to Part 2, Section 5–10–11, of Bombardier Global 5000 BD–700 Time Limits/ Maintenance Checks.

• TR 5–2–44, dated June 4, 2014, to Part 2, Section 5–10–11, of Bombardier Global Express BD–700 Time Limits/ Maintenance Checks. The service information describes procedures for replacing passenger door tensator springs with new springs. This service information is reasonably available because the interested parties have access to it through their normal course of business or by the means identified in the **ADDRESSES** section. FAA’s Determination and Requirements of This Proposed 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 the State of Design Authority, we have been notified of the unsafe condition described in the MCAI and service information referenced above. We are proposing this AD because we evaluated all pertinent information and determined an unsafe condition exists and is likely to exist or develop on other products of these same type designs. Costs of Compliance

We estimate that this proposed AD affects 60 airplanes of U.S. registry.

We also estimate that it would take about 40 work-hours per product to comply with the basic requirements of this proposed AD. The average labor rate is $85 per work-hour. Based on these figures, we estimate the cost of this proposed AD on U.S. operators to be $204,000, or $3,400 per product.

According to the manufacturer, some of the costs of this proposed AD may be covered under warranty, thereby reducing the cost impact on affected individuals. We do not control warranty coverage for affected individuals. As a result, we have included all costs in our cost estimate. 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 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

Air transportation, Aircraft, Aviation safety, Incorporation by reference, Safety. The Proposed Amendment

Accordingly, under the authority delegated to me by the Administrator, the FAA proposes to amend 14 CFR part 39 as follows:

**PART 39—AIRWORTHINESS DIRECTIVES** 

■ 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 adding the following new airworthiness directive (AD):

### 11473 Federal Register / Vol. 81, No. 43 / Friday, March 4, 2016 / Proposed Rules

(e) Reason

This AD was prompted by in-service reports of passenger door tensator spring failures, and qualification testing that determined that incorrect tensator springs could be susceptible to failure prior to reaching their safe-life limit.
