The FAA will also post a report summarizing each substantive verbal contact received about this proposed AD. PO 00000 Frm 00001 Fmt 4702 Sfmt 4702 Discussion The FAA has received a report which indicated that during takeoff, both the captain’s and first officer’s airspeed indications froze at 80 knots. A review of the weather at the departure airport indicated an outside air temperature of 25 degrees Fahrenheit and wind at approximately 20 knots in light snow. The airplane had been waiting in this weather condition for about two hours for de-icing before takeoff. A review of the flight data recorder from this event indicated the airspeed became irregular and could not be read during takeoff until the airplane reached 6,000 feet above ground level. The recorded data also indicated that the pitot tube was possibly blocked with ice. Pitot tubes blocked by ice, if not addressed, could affect the airspeed indication provided to the flightcrew through the ADH system and result in loss of aircraft controllability. Related Service Information Under 1 CFR Part 51 The FAA reviewed Boeing Alert Service Bulletin 717–30A0009, dated March 31, 2020. This service information describes procedures for modifying the ADH system by installing new wires between the station (STA) 110 relay panel and the left radio rack, and doing tests and applicable corrective actions until the tests are passed. 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 The FAA is proposing this AD because the agency 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. Other Relevant Rulemaking Group 1 airplanes in Boeing Alert Service Bulletin 717–30A0009, dated March 31, 2020, are identified as airplanes with a concurrent requirement: Boeing Alert Service Bulletin 717–30A0003. AD 2007–13–01, Amendment 39–15105 (72 FR 33852, June 20, 2007) (‘‘AD 2007–13–01’’) requires accomplishing the actions E:\FR\FM\19JNP1.SGM 19JNP1 37032 Federal Register / Vol. 85, No. 119 / Friday, June 19, 2020 / Proposed Rules specified in Boeing Alert Service Bulletin 717–30A0003, Revision 2, dated November 28, 2006. AD 2007–13– 01 requires operators to accomplish the actions (changing the wiring for the air data sensor heating system) within 24 months after July 25, 2007 (the effective date of AD 2007–13–01). The FAA issued that AD to address the display of suspect or erratic airspeed indications during heavy rain conditions, which could reduce the ability of the flightcrew to maintain the safe flight and landing of the airplane. Since AD 2007–13–01 already requires the concurrent service information, the FAA has not included Boeing Alert Service Bulletin 717–30A0003, Revision 2, dated November 28, 2006, as a concurrent requirement in this proposed AD. Proposed AD Requirements This proposed AD would require accomplishment of the actions identified as ‘‘RC’’ (required for compliance) in the Accomplishment Instructions of Boeing Alert Service Bulletin 717–30A0009, dated March 31, 2020, described previously except for any differences identified as exceptions in the regulatory text of this proposed AD. For information on the procedures and compliance times, see this service information at https:// www.regulations.gov by searching for and locating Docket No. FAA–2020– 0467. Costs of Compliance The FAA estimates that this proposed AD affects 113 airplanes of U.S. registry. The FAA estimates the following costs to comply with this proposed AD: ESTIMATED COSTS FOR REQUIRED ACTIONS Action Labor cost Parts cost Modification * ................................................... 12 work-hours × $85 per hour = $1,020 ........ $4,863 Cost per product $5,883 Cost on U.S. operators $664,779 * The modification costs include the costs for testing. The FAA has received no definitive data on the costs of the corrective actions necessary to pass the testing. 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. khammond on DSKJM1Z7X2PROD with PROPOSALS The FAA has 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 that the proposed regulation: (1) Is not a ‘‘significant regulatory action’’ under Executive Order 12866, (2) Will not affect intrastate aviation in Alaska, and 16:27 Jun 18, 2020 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 Regulatory Findings VerDate Sep<11>2014 (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. Jkt 250001 [Amended] 2. The FAA amends § 39.13 by adding the following new airworthiness directive (AD): ■ The Boeing Company: Docket No. FAA– 2020–0467; Product Identifier 2020– NM–056–AD. (a) Comments Due Date The FAA must receive comments on this AD action by August 3, 2020. (b) Affected ADs None. (c) Applicability This AD applies to all The Boeing Company Model 717–200 airplanes, certificated in any category. PO 00000 Frm 00002 Fmt 4702 Sfmt 4702 (d) Subject Air Transport Association (ATA) of America Code 30, Ice and rain protection. (e) Unsafe Condition This AD was prompted by a report which indicated that during takeoff, both the captain’s and first officer’s airspeed indicators froze at 80 knots. The FAA is issuing this AD to address pitot tubes blocked by ice, which could affect the airspeed indication provided to the flightcrew through the air data heat (ADH) system and result in loss of aircraft controllability. (f) Compliance Comply with this AD within the compliance times specified, unless already done. (g) Required Actions Except as specified in paragraph (h) of this AD: At the applicable times specified in paragraph 1.E., ‘‘Compliance,’’ of Boeing Alert Service Bulletin 717–30A0009, dated March 31, 2020, do all applicable actions identified as ‘‘RC’’ (required for compliance) in, and in accordance with, the Accomplishment Instructions of Boeing Alert Service Bulletin 717–30A0009, dated March 31, 2020. (h) Exception to Service Information Specifications Where Boeing Alert Service Bulletin 717– 30A0009, dated March 31, 2020, uses the phrase ‘‘the original issue date of this service bulletin,’’ this AD requires using ‘‘the effective date of this AD.’’ (i) Alternative Methods of Compliance (AMOCs) (1) The Manager, Los Angeles ACO Branch, FAA, has the authority to approve AMOCs for this AD, if requested using the procedures found in 14 CFR 39.19.

Airworthiness Directives; The Boeing Company Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Notice of proposed rulemaking (NPRM).

-----------------------------------------------------------------------

SUMMARY: The FAA proposes to adopt a new airworthiness directive (AD) 
for all The Boeing Company Model 717-200 airplanes. This proposed AD 
was prompted by a report which indicated that during takeoff, both the 
captain's and first officer's airspeed indications froze at 80 knots. 
This proposed AD would require modifying the air data heat (ADH) system 
to display the proper airspeed indications, testing, and any applicable 
corrective actions. The FAA is proposing this AD to address the unsafe 
condition on these products.

Discussion

    The FAA has received a report which indicated that during takeoff, 
both the captain's and first officer's airspeed indications froze at 80 
knots. A review of the weather at the departure airport indicated an 
outside air temperature of 25 degrees Fahrenheit and wind at 
approximately 20 knots in light snow. The airplane had been waiting in 
this weather condition for about two hours for de-icing before takeoff. 
A review of the flight data recorder from this event indicated the 
airspeed became irregular and could not be read during takeoff until 
the airplane reached 6,000 feet above ground level. The recorded data 
also indicated that the pitot tube was possibly blocked with ice.
    Pitot tubes blocked by ice, if not addressed, could affect the 
airspeed indication provided to the flightcrew through the ADH system 
and result in loss of aircraft controllability.

Related Service Information Under 1 CFR Part 51

    The FAA reviewed Boeing Alert Service Bulletin 717-30A0009, dated 
March 31, 2020. This service information describes procedures for 
modifying the ADH system by installing new wires between the station 
(STA) 110 relay panel and the left radio rack, and doing tests and 
applicable corrective actions until the tests are passed. 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

    The FAA is proposing this AD because the agency 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.

Other Relevant Rulemaking

    Group 1 airplanes in Boeing Alert Service Bulletin 717-30A0009, 
dated March 31, 2020, are identified as airplanes with a concurrent 
requirement: Boeing Alert Service Bulletin 717-30A0003. AD 2007-13-01, 
Amendment 39-15105 (72 FR 33852, June 20, 2007) (``AD 2007-13-01'') 
requires accomplishing the actions

[[Page 37032]]

specified in Boeing Alert Service Bulletin 717-30A0003, Revision 2, 
dated November 28, 2006. AD 2007-13-01 requires operators to accomplish 
the actions (changing the wiring for the air data sensor heating 
system) within 24 months after July 25, 2007 (the effective date of AD 
2007-13-01). The FAA issued that AD to address the display of suspect 
or erratic airspeed indications during heavy rain conditions, which 
could reduce the ability of the flightcrew to maintain the safe flight 
and landing of the airplane. Since AD 2007-13-01 already requires the 
concurrent service information, the FAA has not included Boeing Alert 
Service Bulletin 717-30A0003, Revision 2, dated November 28, 2006, as a 
concurrent requirement in this proposed AD.

Proposed AD Requirements

    This proposed AD would require accomplishment of the actions 
identified as ``RC'' (required for compliance) in the Accomplishment 
Instructions of Boeing Alert Service Bulletin 717-30A0009, dated March 
31, 2020, described previously except for any differences identified as 
exceptions in the regulatory text of this proposed AD.
    For information on the procedures and compliance times, see this 
service information at https://www.regulations.gov by searching for and 
locating Docket No. FAA-2020-0467.

Costs of Compliance

    The FAA estimates that this proposed AD affects 113 airplanes of 
U.S. registry. The FAA estimates the following costs to comply with 
this proposed AD:

  the corrective actions necessary to pass the testing.

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

    The FAA has 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 that the proposed 
regulation:
    (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 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

0
1. The authority citation for part 39 continues to read as follows:

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


Sec.  39.13  [Amended]

0
2. The FAA amends Sec.  39.13 by adding the following new airworthiness 
directive (AD):

The Boeing Company: Docket No. FAA-2020-0467; Product Identifier 
2020-NM-056-AD.

(a) Comments Due Date

    The FAA must receive comments on this AD action by August 3, 
2020.

(b) Affected ADs

    None.

(c) Applicability

    This AD applies to all The Boeing Company Model 717-200 
airplanes, certificated in any category.

(d) Subject

    Air Transport Association (ATA) of America Code 30, Ice and rain 
protection.

(e) Unsafe Condition

    This AD was prompted by a report which indicated that during 
takeoff, both the captain's and first officer's airspeed indicators 
froze at 80 knots. The FAA is issuing this AD to address pitot tubes 
blocked by ice, which could affect the airspeed indication provided 
to the flightcrew through the air data heat (ADH) system and result 
in loss of aircraft controllability.

(f) Compliance

    Comply with this AD within the compliance times specified, 
unless already done.

(g) Required Actions

    Except as specified in paragraph (h) of this AD: At the 
applicable times specified in paragraph 1.E., ``Compliance,'' of 
Boeing Alert Service Bulletin 717-30A0009, dated March 31, 2020, do 
all applicable actions identified as ``RC'' (required for 
compliance) in, and in accordance with, the Accomplishment 
Instructions of Boeing Alert Service Bulletin 717-30A0009, dated 
March 31, 2020.

(h) Exception to Service Information Specifications

    Where Boeing Alert Service Bulletin 717-30A0009, dated March 31, 
2020, uses the phrase ``the original issue date of this service 
bulletin,'' this AD requires using ``the effective date of this 
AD.''

(i) Alternative Methods of Compliance (AMOCs)

    (1) The Manager, Los Angeles 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

[[Page 37033]]

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. Information may be 
emailed to: [email protected].
    (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 The Boeing Company Organization Designation 
Authorization (ODA) that has been authorized by the Manager, Los 
Angeles ACO Branch, FAA, 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.
    (4) For service information that contains steps that are labeled 
as Required for Compliance (RC), the provisions of paragraphs 
(i)(4)(i) and (ii) of this AD apply.
    (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. If a step or substep is labeled ``RC Exempt,'' then the 
RC requirement is removed from that step or substep. 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.
