AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Final rule. 

SUMMARY: The FAA is adopting a new 

airworthiness directive (AD) for all 

Piper Aircraft, Inc., (Piper) Models PA– 

46–350P (Malibu Mirage), PA–46R– 

350T (Malibu Matrix), and PA–46– 

500TP (Malibu Meridian) airplanes. 

This AD was prompted by a finding of 

several airplanes with wing assemblies 

that did not have the proper stall 

warning heater modification design. 

Without the proper stall warning heat 

control modification kit installed, 

during flights into icing conditions with 

the landing gear down, ice can form on 

the stall vane, which may result in 

failure of the stall warning system. This 

AD requires identifying and correcting 

nonconforming stall warning heat 

control systems. The FAA is issuing this 

AD to address the unsafe condition on 

these products. 

DATES: This AD is effective March 30, 

2021. 

The Director of the Federal Register 

approved the incorporation by reference 

of a certain publication listed in this AD 

as of March 30, 2021.

SUPPLEMENTARY INFORMATION: 

Background 

The FAA issued a notice of proposed 

rulemaking (NPRM) to amend 14 CFR 

part 39 by adding an AD that would 

apply to all Piper Models PA–46–350P 

(Malibu Mirage), PA–46R–350T (Malibu 

Matrix), and PA–46–500TP (Malibu 

Meridian) airplanes. The NPRM 

published in the Federal Register on 

October 28, 2020 (85 FR 68255). The 

NPRM was prompted by the finding of 

Federal Register / Vol. 86, No. 34 / Tuesday, February 23, 2021 / Rules and Regulations 10771 

airplanes without the proper stall 

warning heater modification design 

change. In the NPRM, the FAA 

proposed to require identifying and 

correcting nonconforming stall warning 

heat control systems. 

The FAA issued AD 2008–26–11, 

Amendment 39–15777 (73 FR 78934, 

December 24, 2008) (‘‘AD 2008–26–11’’) 

for certain serial-numbered Piper Model 

PA–46–350P, PA–46R–350T, and PA– 

46–500TP airplanes. AD 2008–26–11 

requires installing stall warning heat 

control modification kit part number 

88452–002. For those serial-numbered 

airplanes to which AD 2008–26–11 does 

not apply, Piper incorporated the 

modification kit in production. 

Since the FAA issued AD 2008–26– 

11, Piper found 11 airplanes (9 

domestic) with the left wing replaced 

with a wing assembly from salvage that 

did not have the proper stall warning 

heater modification design change. 

Without the proper stall warning heat 

control modification kit during flights 

into icing conditions with the landing 

gear down, ice can form on the stall 

vane, which may result in failure of the 

stall warning system. The FAA is 

issuing this AD to address the unsafe 

condition on these products. 

This action will not affect AD 2008– 

26–11 and all actions of that AD will 

remain in place. 

Discussion of Final Airworthiness 

Directive 

Comments 

The FAA received a comment from 1 

commenter. The commenter supported 

the NPRM without change. 

Conclusion 

The FAA reviewed the relevant data, 

considered the comments received, and 

determined that air safety requires 

adopting the AD as proposed. 

Accordingly, the FAA is issuing this AD 

to address the unsafe condition on these 

products. Except for minor editorial 

changes, this AD is adopted as proposed 

in the NPRM. 

Related Service Information Under 1 

CFR Part 51 

The FAA reviewed Piper Service 

Letter No. 1261, dated July 19, 2019. 

This service information specifies 

procedures to identify and correct 

nonconforming stall warning heat 

control systems. The intent of these 

service letters is to ensure that wiring 

for the stall warning heat control system 

meets current type design. 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 ADDRESSES. 

Other Related Service Information 

The FAA reviewed Piper Mandatory 

Service Bulletin No. 1192, dated 

September 15, 2008. This service 

bulletin is incorporated by reference in 

AD 2008–26–11. 

Differences Between This AD and the 

Service Information 

This AD does not require the first 

step, which is identified as a ‘‘required 

for compliance’’ (RC) step, of Piper 

Service Letter No. 1261, dated July 19, 

2019. The first step specifies reviewing 

the aircraft records to determine 

whether the inspection of the stall 

warning heat control configuration must 

be done. This AD does not require a 

records review. Instead, all airplanes 

identified in the applicability of this AD 

have to inspect the stall warning heat 

control configuration. 

Costs of Compliance 

The FAA estimates that this AD will 

affect 1,261 airplanes of U.S. registry. 

The FAA estimates the following 

costs to comply with this AD: 

ESTIMATED COSTS

Action Labor cost Parts cost Cost per 

product 

Cost on U.S. 

operators 

Inspect stall warning heat control system ...... 1 work-hour × $85 per hour = $85 ................. $0 $85 $107,185 

The FAA estimates the following 

costs to do any necessary repairs that 

will be required based on the results of 

the inspection. The FAA has no way of 

determining the number of airplanes 

that might need these repairs: 

ON-CONDITION COSTS

Action Labor cost Parts cost Cost per 

product 

Install modification kit ................................................... 1.5 work-hours × $85 per hour = $127.50 ................... $230.00 $357.50 

The FAA has included all known 

costs in its cost estimate. According to 

the manufacturer, however, some or all 

of the costs of this AD may be covered 

under warranty, thereby reducing the 

cost impact on affected individuals. 

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. 

The FAA is 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 

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: 

10772 Federal Register / Vol. 86, No. 34 / Tuesday, February 23, 2021 / Rules and Regulations 

(1) Is not a ‘‘significant regulatory 

action’’ under Executive Order 12866, 

(2) Will not affect intrastate aviation 

in Alaska, 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. 

List of Subjects in 14 CFR Part 39 

Air transportation, Aircraft, Aviation 

safety, Incorporation by reference, 

Safety. 

The Amendment 

Accordingly, under the authority 

delegated to me by the Administrator, 

the FAA amends 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: 

2021–04–07 Piper Aircraft, Inc.: 

Amendment 39–21428; Docket No. 

FAA–2020–0830; Project Identifier 

2020–CE–002–AD. 

(a) Effective Date 

This airworthiness directive (AD) is 

effective March 30, 2021. 

(b) Affected ADs 

None. 

(c) Applicability 

(c) This AD applies to the following Piper 

Aircraft, Inc., airplanes, certificated in any 

category: 

(1) Model PA–46–350P (Malibu Mirage) 

airplanes, serial numbers (S/Ns) 4622041, 

4636041, 4636142, 4636143, 4636313, 

4636341, and 4636379; 

(2) Model PA–46–500TP (Malibu Meridian) 

airplanes, S/Ns 4697141, 4697161, 4697086, 

and 4697020; and 

(3) Models PA–46–350P (Malibu Mirage), 

PA–46R–350T (Malibu Matrix), and PA–46– 

500TP (Malibu Meridian) airplanes, all serial 

numbers, if the left wing has been replaced 

with a serviceable (more than zero hours 

time-in-service) wing. 

(d) Subject 

Joint Aircraft System Component (JASC) 

3700, VACUUM SYSTEM. 

(e) Unsafe Condition 

This AD was prompted by nonconforming 

stall warning heat control systems, utilizing 

a left wing assembly without the proper stall 

warning modification design. Without the 

proper stall warning heat control 

modification kit during flights into icing 

conditions with the landing gear down, ice 

can form on the stall vane, which may result 

in failure of the stall warning system. The 

FAA is issuing this AD to identify and 

correct nonconforming stall warning heat 

control systems. The unsafe condition, if not 

addressed, could result in the pilot being 

unaware of an approaching stall situation. 

(f) Compliance 

Comply with this AD within the 

compliance times specified, unless already 

done. 

(g) Actions 

(1) Within 100 hours time-in-service (TIS) 

after the effective date of this AD or within 

12 months after the effective date of this AD, 

whichever occurs first, inspect the 

configuration of stall warning heat control 

system and, if required, install stall warning 

heat control modification kit part number 

(P/N) 8452–002 before further flight in 

accordance with steps 2 and 3 of the 

Instructions in Piper Aircraft, Inc., Service 

Letter No. 1261, dated July 19, 2019. 

(2) As of the effective date of this AD, do 

not install a wing on any Model PA–46–350P 

(Malibu Mirage), PA–46R–350T (Malibu 

Matrix), or PA–46–500TP (Malibu Meridian) 

airplane unless you have determined that the 

wing has the correct stall warning heat 

control system as required by paragraph 

(g)(1) of this AD. 

(h) Special Flight Permit 

A special flight permit may be issued to 

operate the airplane to a location where the 

requirements of this AD can be accomplished 

provided flight into known icing conditions 

is prohibited. 

(i) Alternative Methods of Compliance 

(AMOCs) 

(1) The Manager, Atlanta ACO Branch, 

FAA, has the authority to approve AMOCs 

for this AD, if requested using the procedures 

found in 14 CFR 39.19. In accordance with 

14 CFR 39.19, send your request to your 

principal inspector or local Flight Standards 

District Office, as appropriate. If sending 

information directly to the manager of the 

certification office, send it to the attention of 

the person identified in paragraph (j)(1) of 

this AD. 

(2) Before using any approved AMOC, 

notify your appropriate principal inspector, 

or lacking a principal inspector, the manager 

of the local flight standards district office/ 

certificate holding district office. 

(3) An AMOC that provides an acceptable 

level of safety may be used for any repair, 

modification, or alteration required by this 

AD if it is approved by a Piper Aircraft, Inc. 

Organization Designation Authorization 

(ODA) that has been authorized by the 

Manager, Atlanta ACO Branch to make those 

findings. To be approved, the repair method, 

modification deviation, or alteration 

deviation must meet the certification basis of 

the airplane, and the approval must 

specifically refer to this AD. 

(i) The steps labeled as RC, including 

substeps under an RC step and any figures 

identified in an RC step, must be done to 

comply with the AD. An AMOC is required 

for any deviations to RC steps, including 

substeps and identified figures. 

(ii) Steps not labeled as RC may be 

deviated from using accepted methods in 

accordance with the operator’s maintenance 

or inspection program without obtaining 

approval of an AMOC, provided the RC steps, 

including substeps and identified figures, can 

still be done as specified, and the airplane 

can be put back in an airworthy condition.
