Waiver of Flight Termination Receiver Qualification by Similarity 
Deficiencies

AGENCY: Federal Aviation Administration (FAA), Department of 
Transportation (DOT).

ACTION: Notice of waiver.

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

SUMMARY: This notice concerns three petitions for waiver submitted to 
the FAA by Rocket Lab USA Inc. (RL) for the Flight Termination Receiver 
(FTR) Qualification by Similarity (QBS): A petition to waive the 
requirement that a component may be qualified based on similarity to a 
component that has already been qualified for use only if the 
environments encountered by the previously qualified component during 
its qualification or flight history were equal or more severe than the 
Rocket Lab qualification environments; a petition to waive the 
Electromagnetic Interference and Compatibility (EMI/EMC) on the same 
units; and a petition to waive the requirement that the same 
manufacturer must produce the qualified and the unqualified component 
in the same location using identical tools and manufacturing processes. 
The FAA grants these three petitions.

DATES: Issued in Washington, DC, on May 15, 2017.

SUPPLEMENTARY INFORMATION:

Background

    RL submitted a petition to the FAA's Office of Commercial Space 
Transportation (AST) requesting relief from regulatory requirements for 
a launch license for flight of Electron test flight missions from 
Mahia, New Zealand. Specifically, RL requested relief from 14 CFR 
E417.7(f)(2) and (5), Qualification Testing and Analysis by Similarity 
for the Flight Termination Receiver. For Qualification, the Flight 
Termination Receiver is required to meet Table E417.19-2, which states 
with note (5): ``The same three sample components must undergo each 
test designated with an X. For a test designated with a quantity of 
less than three, each sample component tested must be one of the 
original three sample components.'' For Qualification Testing and 
Analysis by Similarity, Part 417 Appendix E section 417.7(f) provides 
the requirements a launch operator must satisfy in order to qualify or 
re-qualify a flight termination system component's design through 
qualification by similarity to tests performed on identical or similar 
hardware. Section E417.7(f)(2) states that to qualify component ``A'' 
based on similarity to

[[Page 29799]]

component ``B'', that has already been qualified for use, a launch 
operator must demonstrate that the environment encountered by ``B'' 
must have been equal to or more severe than the qualification 
environments required for ``A''. Specifically, RL used different 
components for the random vibration qualification test and the EMI/EMC 
qualification test instead of the original three qualification sample 
components used for the other tests under E417.7(f)(2). Section 
E417.7(f)(5) requires that the same manufacturer produce ``A'' and 
``B'' in the same location using identical tools and manufacturing 
processes. Specifically, RL's sample ``A'' and ``B'' were manufactured 
at different locations with different manufacturing processes.
    The FAA licenses the launch of a launch vehicle and reentry of a 
reentry vehicle under authority granted to the Secretary of 
Transportation in the Commercial Space Launch Act of 1984, as amended 
and re-codified by 51 U.S.C. Subtitle V, chapter 509 (Chapter 509), and 
delegated to the FAA Administrator and the Associate Administrator for 
Commercial Space Transportation, who exercises licensing authority 
under Chapter 509.
    RL is a private commercial space flight company. RL seeks to lower 
the cost and increase the frequency of access to space for small 
payloads, potentially expanding the opportunity for space services and 
research. RL's petition for waiver addresses all upcoming Electron test 
flights that RL plans to launch from the Mahia Peninsula, New Zealand. 
The Electron launch is the first planned test flight from the 
privately-owned Rocket Lab Launch Complex at Mahia Peninsula in Hawkes 
Bay, New Zealand. The launch location is capable of hosting launches to 
the northeast, east, and south. The area within 20 NM surrounding the 
launch site is extremely remote, and has a low population density. The 
launch flight corridor will have minimal impact on air and marine 
traffic.

Waiver Criteria

    Chapter 509 allows the FAA to waive a license requirement if the 
waiver (1) will not jeopardize public health and safety, safety of 
property; (2) will not jeopardize national security and foreign policy 
interests of the United States; and (3) will be in the public interest. 
See 51 U.S.C. 50905(b)(3) (2011); 14 CFR 404.5(b) (2011).

Section E417.7(f)(2) and (5) Waiver Petition

    Section E417.7(f)(2) requires a launch operator wishing to qualify 
a component's design through qualification by similarity to tests 
performed on identical or similar hardware to demonstrate that the 
environments encountered by the component during its qualification or 
flight history were equal to or more severe than the qualification 
environments required for a component that has already been qualified 
for use. Section E417.7(f)(5) requires a launch operator qualifying a 
component's design as discussed above to demonstrate that the same 
manufacturer produced both the qualified component and the component 
the launch operator wishes to qualify in the same location using 
identical tools and manufacturing processes. For reasons described 
below, the FAA waives the requirements in section E417.7(f)(2) and (5) 
to allow RL to use components in its flight termination system that 
were qualified by similarity to more than one qualified component.
    In deciding whether or not to issue a waiver, the FAA had to 
analyze whether the waiver: (1) Would jeopardize public health and 
safety or safety of property; (2) would jeopardize national security 
and foreign policy interests of the United States; and (3) was in the 
public interest. See 51 U.S.C. 50905(b)(3); 14 CFR 404.5(b).

i. Public Health and Safety and Safety of Property

    Part 417 contains requirements for qualification and acceptance 
testing of flight termination system components based on the approach 
used at the federal launch ranges. At federal launch ranges, flight 
termination system components are tested according to federal range-
approved test procedures and requirements. Verification methods include 
test, analysis, and inspection. As an alternative to testing, 
components of an FTS are sometimes qualified by similarity. A component 
that has been qualified through testing for one launch vehicle may be 
approved for use on a different launch vehicle if it can be shown that 
the environments in which it must operate on the second vehicle are no 
harsher than those of the first. Also, with limited additional testing, 
the component may be qualified for a more severe environment. Although 
RL did not complete each of the qualification by similarity 
requirements for its flight termination receiver as required by the 
regulations, the failsafe design of the Electron's flight termination 
system combined with the remoteness of the operating area allow the FAA 
to find that RL's activities will not jeopardize public health and 
safety and safety of property.
    RL procured the Electron launch vehicle's flight termination 
receiver from Vendor A, who performed several qualification and delta 
qualification tests. A delta qualification test extends the tested 
environments to cover specific tests or levels that were not previously 
covered. RL submitted a Qualification by Similarity Analysis Report to 
the FAA, referencing three previous groups of similar flight 
termination receiver qualification and delta qualification tests 
performed by Vendor A. Group 1 was subjected to most of the 
qualification testing required by 14 CFR Table E417.19-2, with three 
exceptions: (a) Group 1 did not satisfy 14 CFR E417.7(f)(2) because the 
random vibration qualification environment encountered by Group 1 was 
not equal to or more severe than the random vibration qualification 
environment required for the Electron flight termination receivers, 
falling below for approximately 3.5% over the required 20 Hz to 2000 Hz 
test band; (b) Group 1 was not subjected to EMI/EMC testing; and (c) 
Group 1 did not meet the requirements of 14 CFR E417.7(f)(5) because it 
was not produced in the same manufacturing location using identical 
tools and manufacturing processes as the Rocket Lab Electron flight 
termination receivers. Group 1's deficiencies were mitigated by two 
subsequent delta qualification tests on 2 groups (referred to herein as 
Group 2 and Group 3) of similar receivers. Group 2 satisfied Electron's 
required random vibration qualification test levels for the entire 
required test band, and Group 2 was manufactured in the same location 
using identical tools and manufacturing processes as Electron flight 
termination receivers. Group 3 successfully passed EMI/EMC 
qualification testing.
    Group 1 also did not meet the requirements of 14 CFR E417.7(f)(5) 
because Group 1 was not produced in the same manufacturing location 
using identical tools and manufacturing processes as Group 2 and 
Electron flight termination receivers. Vendor A originally outsourced 
one of the flight termination receiver's printed circuit boards to 
another supplier. In late 2013, Vendor A upgraded its internal 
equipment and process, and assembled the printed circuit boards in-
house. Group 1 and Group 3 were manufactured and qualification tested 
before this change in equipment and process, whereas Group 2 and 
Electron's flight termination receivers were assembled after the 
change. To verify that the equipment and process change did not 
invalidate previous qualification and delta qualification testing, 
Vendor

[[Page 29800]]

A applied the same heritage process profile to the new equipment, 
retained heritage printed circuit board samples for periodic process 
control comparisons, and implemented periodic visual/x-ray inspections 
for consistency validation. Heritage and new equipment specifications 
were also assessed to compare their performance characteristics. White 
Sand Missile Range has reviewed and accepted this process change, for 
U.S. Government launch vehicle programs conducting launches from its 
launch range, based on improved reliability and quality of the process.
    The FAA waives the requirements of E417.7(f)(2) and (5) because the 
Electron has implemented a failsafe flight safety system design that 
would terminate thrust to the vehicle should both flight termination 
receivers fail or communication was lost with the ground station, and 
RL's operating area is remote enough that were it to experience a 
catastrophic failure, it would not jeopardize public health and safety 
and safety of property. The Electron test flight missions would occur 
from the isolated Mahia Peninsula in New Zealand. The area within 20 NM 
of Mahia Peninsula has a very low population density. The Electron 
flight corridor is over the broad ocean area with minimal impact on air 
and marine traffic. Consequence analysis showed that less than 1 in 
100,000 casualties would be expected if the worst foreseeable vehicle 
response mode (i.e., where the vehicle guidance is assumed to fail in a 
manner that leads to an attempt to guide to erroneous, randomly located 
points) occurred at the worst flight time (relatively early in flight 
before the vehicle proceeds downrange) and the flight termination 
receiver failed to activate. Thus, the casualty expectation given the 
assumption of the worst possible failure would on average still produce 
significantly less casualties than the FAA's limit of 1 in 10,000, 
which does not assume failure but rather assigns realistic failure 
probabilities. Also, the flight termination receiver's failsafe feature 
will terminate thrust if there is a loss of power or Radio Frequency 
carrier or pilot tone signal, providing an additional safety margin. 
For these reasons, the FAA has determined that waiving sections 
E417.7(f)(2) and (5) for the Electron test flight missions from Mahia, 
New Zealand will not jeopardize public health and safety or safety of 
property.

ii. National Security and Foreign Policy Implications

    The FAA has identified no national security or foreign policy 
implications associated with granting this waiver.

iii. Public Interest

    The waiver is consistent with the public interest goals of Chapter 
509 and the National Space Transportation Policy. Three of the public 
policy goals of Chapter 509 are: (1) To promote economic growth and 
entrepreneurial activity through use of the space environment; (2) to 
encourage the United States private sector to provide launch and 
reentry vehicles and associated services; and (3) to facilitate the 
strengthening and expansion of the United States space transportation 
infrastructure to support the full range of United States space-related 
activities. See 51 U.S.C. 50901(b)(1), (2), (4).
    RL seeks to lower the cost and increase the frequency of access to 
space for small payloads, potentially expanding the opportunity for 
space services and research. These activities will help to make the 
U.S. launch industry more competitive internationally. The National 
Space Transportation Policy states that strengthening U.S. 
competitiveness in the international launch market and improving the 
cost effectiveness of U.S. space transportation services are in the 
public interest:
    Maintaining an assured capability to meet United States Government 
needs, while also taking the necessary steps to strengthen U.S. 
competitiveness in the international commercial launch market, is 
important to ensuring that U.S. space transportation capabilities will 
be reliable, robust, safe, and affordable in the future. Among other 
steps, improving the cost effectiveness of U.S. space transportation 
services could help achieve this goal by allowing the United States 
Government to invest a greater share of its resources in other needs 
such as facilities modernization, technology advancement, scientific 
discovery, and national security. Further, a healthier, more 
competitive U.S. space transportation industry would facilitate new 
markets, encourage new industries, create high technology jobs, lead to 
greater economic growth and security, and would further the Nation's 
leadership role in space.
    More specifically, Rocket Lab will be carrying onboard the Electron 
launch vehicle on its inaugural launch a flight test experiment for 
NASA Kennedy Space Center which will improve public risk mitigation 
capabilities from an errant launch vehicle. This component is designed 
and manufactured by NASA KSC and is part of the independent safety 
system which will be installed on the launch vehicles. This safety 
system will be capable of determining if the flight of the launch 
vehicle will pose an unacceptable increased risk to the public based on 
mission rules designed for its unique vehicle and flight 
characteristics and programmed into the safety system and terminate the 
flight of such launch vehicle. This type of capability is in public 
interest because this safety system will allow for improved protection 
of the public from mishaps resulting from flight of errant launch 
vehicles.
