The Installation Instructions and Limitations (IIL) contained in this document are applicable to the seat
assembly part numbers listed in Table 1. For other seat assemblies in this seat model family refer to IILs
applicable to those seats.
Note that the conditions and tests required for TSO approval of the subject articles are minimum
performance standards. It is the responsibility of those desiring to install the article(s) either on or within
a specific type or class of aircraft to determine that the aircraft installation conditions are within TSO
standards. The article(s) may be installed only if the installation is performed in accordance with 14 CFR
Part 43 or the applicable airworthiness requirements.

The maximum certified seat weight is the maximum allowable weight for the seat with all items contained in the bill of materials installed
including occupant restraints, IFE, and dress covers. It does not include any equipment the seat installer may add to the seat, such as
emergency equipment or literature pocket contents. This weight may exceed production seat weight. This weight does not include 3%
allowance per AC25.562-1B, Appendix 3, Section 16.b(1).

The miscellaneous storage accounts for any additional storage provisioned such as magazines, water bottles, etc. except conventional
underseat baggage weight (if applicable).
4
The maximum installed seat weight is the maximum allowable weight for the seat with all components and includes all equipment the seat
installer may add to the seat, such as emergency equipment or literature pocket contents. This weight is equal to the minimum total tested
seat weight of all static/dynamic tests used for substantiation of the subject seat P/Ns. However, this weight must be verified against seat
track interface loads and other aircraft/structural limitations.

Seat P/Ns 1017016-001HF08/002HF08 can only be installed behind any seat P/N at a pitch of 30-34" excluding seat P/N 1017014-013HF08 which can only be installed at a seat pitch of 31".
This also applies to the opposite seat hand P/N 1017016-002HF08 behind seat P/N 1017014-014HF08. See Figure 19 for more detail.

Front Row Seat P/N 1017014-103HF08
Test WS5214, per DTR1933, established the front row head path for seat part number 1017014-103HF08 per
ARP5482. The head path data is more critical than the knee path data and is therefore used for installation
th
limitations. The data below illustrates the path of the top of the head for the respective 50 percentile ATD. The
values are referenced from the front stud and the top of track.

For the I/B pax the knee path data was measured at the knee pivot, an additional 2.4" needs to be added to get
the location of the front of the knee. This measurement is calculated from Appendix J on page J32 as "Knee
Front" - "Knee Pivot" (37.2" - 34.8" = 2.4"). Per Figure 15 the maximum knee pivot excursion is 13.52" which
would give a maximum front of knee excursion of 15.92"

For the O/B pax the knee path data was measured at the knee pivot, an additional 2.4" needs to be added to get
the location of the front of the knee. This measurement is calculated from Appendix J on page J37 as "Knee
Front" - "Knee Pivot" (36.9" - 34.5" = 2.4"). Per Figure 15 the maximum knee pivot excursion is 8.02" which would
give a maximum front of knee excursion of 10.42"

Double seat P/N 1017016-001HF08 can be installed behind any seat P/N at a pitch of 30-34" except when
installed behind seat P/N 1017014-013HF08. Then seat P/N 1017016-001HF08 must be installed behind triple
seat P/N 1017014-013HF08 in the configuration shown in Figure 19 below at a 31” seat pitch. The seats must
also be installed in the aft portion of the aircraft canted at 4.26º. This also applies to the opposite seat hand P/N
1017016-002HF08 behind seat P/N 1017014-014HF08. Seat P/Ns 1017016-001HF08/002HF08 are not qualified
for HIC/Femur, therefore seats cannot be installed behind these seats.

Figure 19 Special Installation for Seat P/N 1017016-001HF08 behind Seat P/N 1017014-013HF08
Front row seat P/Ns 1017014-101HF08/102HF08 have two head/knee paths, one for the O/B pax and one for the
I/B and CTR pax. The I/B & CTR pax have a maximum top of head excursion of 28.07" and maximum knee
excursion of 15.92" while the O/B pax has a head excursion of 21.3" and a maximum knee excursion of 10.42".
The installer must take this into consideration when approving the seat installation particularly when installing the
seat behind a door bustle.

Installation Instructions
(1) Verify seat installation location using installation drawing. Pay particular attention to seats spanning
track breaks at transition from constant section to non-constant section of aircraft, if applicable.
(2) Place track studs and track fittings at base of each leg assembly into corresponding openings in
aircraft seat tracks. Ensure that seat is not racked with respect to aircraft seat tracks.
(3) Slide seat assembly forward or aft approximately one half inch until locking mechanism on track fitting
can be pressed into seat track opening.
(4) To lock track fitting into position, use torque wrench to tighten Allen setscrew on top of fitting. This
will push shear plunger against top surface of aircraft seat tracks. Be certain to apply torque specified
on installation drawing to complete seat installation.
(5) Tighten anti-rattle nut or track adapter floor attachment bolts under forward portion of each leg to
torque specified on installation drawing. If no torque is specified, lift seat between track lip and front
stud to ensure no gap and shaking; tighten anti-rattle device by hand and then tighten additional ¼-
turn using anti-rattle nut wrench until secure in seat track.
(6) Verify seat is installed in correct location per installation drawing.
(7) If seat is equipped with in-seat electrical cabling, connect in-seat electrical cabling to aircraft seat-to-
seat cables in accordance with aircraft electrical installation drawing.
• The seat part numbers listed in Table 7 below have been evaluated for installation adjacent to Type III
Exits in the airframe listed in this IIL. The seat installer is responsible for using the test data provided in
the referenced test report(s) to evaluate egress requirements for the seat-to-seat pitch listed below.

• The seat assemblies contain integrated electronic equipment that is covered under the seat TSO
authorization per option 7b of AC21-49. The TSO approval of the subject seat assemblies cover the
attributes of the integrated electronic components for the attributes listed in Table 1 of AC21-49. The TC
or STC applicant for the seat system installation on the aircraft is responsible for all other regulatory
requirements associated with the integrated electronic components.
