Federal Register Proposed Rules, Rules and Notices for July 18,2013

July 18,2013

NOTICES

Membership Availability in the National Parks Overflights Advisory Group
Aviation Rulemaking Committee [FR DOC# 2013-17254] SUMMARY: The National
Park Service (NPS) and the Federal Aviation Administration (FAA), as
required by the National Parks Air Tour Management Act of 2000, established
the National Parks Overflights Advisory Group (NPOAG) in March 2001. The
NPOAG was formed to provide continuing advice and counsel with respect to
commercial air tour operations over and near national parks. This notice
informs the public of two vacancies on the NPOAG [now the NPOAG Aviation
Rulemaking Committee (ARC)] for members representing commercial air tour
operators (one vacancy) and environmental concerns (one vacancy) and invites
interested persons to apply to fill the vacancies.

Waiver of 14 CFR 437.29 and 437.55(a) for Scaled Composites, LLC [FR DOC#
2013-17169] SUMMARY: This notice concerns a waiver to Scaled Composites, LLC
(Scaled) from the requirements of 14 CFR 437.29 and 437.55(a) to provide the
FAA a hazard analysis that identifies, mitigates, and verifies and validates
mitigation measures for hazards created by software and human error. The FAA
finds that a waiver is in the public interest and will not jeopardize public
health and safety, safety of property, and national security and foreign
policy interests of the United States.

PROPOSED RULES

Airworthiness Directives; Bombardier, Inc. Airplanes [FR DOC# 2013-17255]
SUMMARY: We propose to adopt a new airworthiness directive (AD) for certain
Bombardier, Inc. Model BD-700-1A11 airplanes. This proposed AD was prompted
by a report that certain lanyards for the passenger oxygen masks are longer
than the specified length, possibly leading to inactive oxygen masks in an
emergency. This proposed AD would require replacing certain oxygen mask
lanyards. We propose this AD to detect and correct lanyards of incorrect
length, which might not activate the flow of oxygen in an emergency,
resulting in injury to passengers.

Airworthiness Directives; The Boeing Company Airplanes [FR DOC# 2013-17253]
SUMMARY: We propose to adopt a new airworthiness directive (AD) for certain
The Boeing Company Model 727-200 and 727-200F series airplanes. This
proposed AD is intended to complete certain mandated programs intended to
support the airplane reaching its limit of validity (LOV) of the engineering
data that support the established structural maintenance program. This
proposed AD would require a one-time inspection for cracking of the pressure
floor of both main wheel wells, and related investigative and corrective
actions if necessary; and would require modifying the pressure floor of both
main wheel wells. We are proposing this AD to prevent fatigue cracking in
the pressure floor of the main wheel wells, which could lead to rapid loss
of cabin pressurization.

Airworthiness Directives; ATR-GIE Avions de Transport Régional Airplanes [FR
DOC# 2013-17293] SUMMARY: We propose to adopt a new airworthiness directive
(AD) for certain ATR-GIE Avions de Transport R[eacute]gional Model ATR72-
101, – 201, -102, -202, -211, -212, and -212A airplanes. This proposed AD
was prompted by reports of airplane incidents and accidents that have
occurred because of low-level fuel tank situations and fuel starvation that
resulted in engine flameouts. This proposed AD would require installing a
fuel quantity indicator (FQI) equipped with a locking adaptor on the
electrical connector. We are proposing this AD to prevent an engine flame-
out, which could result in reduced controllability of the airplane.

Airworthiness Directives; The Boeing Company Airplanes [FR DOC# 2013-17252]
SUMMARY: We propose to adopt a new airworthiness directive (AD) for certain
The Boeing Company Model 727 airplanes. This proposed AD is intended to
complete certain mandated programs intended to support the airplane reaching
its limit of validity (LOV) of the engineering data that support the
established structural maintenance program. This proposed AD would require
an inspection for cracks in the main wheel well pressure floor and a
preventive modification or permanent repair, as applicable. We are proposing
this AD to prevent cracking in the main wheel well pressure floor, which
could result in reduced structural integrity of the airplane, and
decompression of the cabin.
