1 Bell 412EPx and 407GXi Paint Scheme – do you want to match N11PP’s paint scheme? Or if a new paint scheme is desired.

OEM-applied exterior paint. Multi-color, high-visibility finish of moderate-to-high complexity, including standard agency markings (e.g., badges, identification lettering, and registration numbers). Final specifications will be provided prior to production.

2 Can you please provide paint codes and a high-resolution file of the USPP badge?

OEM-applied exterior paint. Multi-color, high-visibility finish of moderate-to-high complexity, including standard agency markings (e.g., badges, identification lettering, and registration numbers). Final specifications will be provided prior to production.

Both 412 & 407; B7.X.X – Motorola Radios. Bell will install the provisions including mounting and adapters for the Motorola Radios; the actual radios need to be Customer Furnished Equipment because they are non-aviation radios.

B7.3.5 and B7.3.6 have been updated accordingly.

Bell 412EPx and 407GXi; B7.3.7 – Loudspeaker System. External public address/siren system (PA) providing 75 watts RMS would be Ok for siren broadcasting. Recommend a 600 watts RMS if clear, air-to-ground voice broadcast (typical law enforcement or SAR) is desired. Is 75 watts RMS sufficient for your mission?

B7.3.7 in the 412EPX and 407GXi Sections have been updated accordingly.

5 Bell 412EPx and 407GXi; Section B – FLIR Camera Systems. No options were specified for the sensor. Is the basic sensor sufficient or are there any options required? B6.17 and B6.21 have been updated accordingly.

412EPx and 407GXi; B7.3.3 – Three police band FM radio transceiver and control systems… The systems’ operational control frequency range must include the following frequency bands:

a. VHF-low (29.7Mhz-50Mhz analog) **should read 30 to 50MHz

b. VHF-high (138MHz-174MHz) **should read 136-174MHz

c. UHF (406MHz-512MHz) **should read 380-520 MHz

d. 700MHz (698MHz – 806MHz) **700-800 are a combined band running 764-870MHz. There is no 698-806 band.

e. 800MHz (790MHz-862MHz) ** Ok ** please see notes regarding specified frequencies

B7.3.3 has been updated to include subsections B7.3.3.1, B7.3.3.2, and B7.3.3.3, and the frequency ranges have been revised accordingly.

7 Bell 412EPx; section B6; item B6.11.2 – Aft Cabin “Space Doors”. Dart “Space Doors” are no longer procurable. Are standard sliding doors acceptable? B6.11.2 has been deleted.

8 Bell 412IPx; B6.6; Aircraft Floor Covers – Alpine Aerotech offers composite floor panels( AAL-212-020-905). Is this design what you are looking for? B6.6 has been updated.

9 Bell 412EPx; B6.15.3; Hard Mount Wall Fastener (human cargo rated) – Bell is not aware of a human cargo approved wall fastener. Is there a specific product you have in mind? B6.15.3 has been updated.

10 Bell 412EPx; B6.15.4; Hard Mount Ceiling HEC Fastener Points – Bell is not aware of a certified hard mount ceiling HEC attach point. In B.6.15.1, Dart Heli-Rappel (L and R) is specified. Is this sufficient? B6.15.4 has been updated.

Bell 412EPx; B6.18. Frahm Damper – Although still available, Bell has found the Frahm Damper is not necessary on the 412EPx. Removing this requirement provides a 19 LB weight savings. Do you want to remove this item?

B6.18 has been deleted.

Bell 412EPx; B6.22; Floor Tracks/Rapid Configuration Equipment Management System – With the LifePort HEMS kit installed, floor tracks are not advised. The cabin floor “pucks” are available and can be used for easy seat reconfiguration if needed. Is this acceptable?

Cabin floor pucks do not fully meet USPP operational requirements.

13 Bell 412EPx; B6.23; Airframe Fuel Filter – The Bell 412EPx utilizes a fuel filter incorporated into the engines.

An airframe mounted fuel filter is not available B6.23 has been deleted.

Bell 412EPx; B6.24 and B6.44; Crew Chief Seat – Bell intends to use the LifePort Mission Seat for this requirement. It appears B6.24 and B6.44 are calling for the same item (crew chief seat). The LifePort Mission Seat has 4-point restraint and swivels. Is this acceptable?

B6.24 has been deleted.

B6.44 has been updated.

Bell 412EPx; B6.34 and B6.37; Induction Baffle Access/Plenum Access – This access has been incorporated into the 412EPx base aircraft. It appears B6.34 and B6.37 are calling for the same item. Please let us know if this is not the case.

Bell 412EPx as offered meets this requirement.

18 Bell 412EPx; B7.6.2; 7” Monitor with Synthetic Vision – The only synthetic vision option available for the 412EPx would be through Garmin Pilot and displayed on iPads (customer furnished equipment). Is this acceptable? B7.6.2 has been updated.

19 Bell 407GXi; section B2; Certifications – IFR. Just confirming IFR is desired on the 407. IFR in Section B2 of the 407GXi has been removed.

Bell 407GXi; section B6; B6.7.1 – Energy Attenuating Pilot and Copilot Seats. The 407 crew seats are not considered “energy attenuating”. They incorporate “crush panels” in the lower structure designed to “absorb” energy in a hard landing, etc. Is this design acceptable?

This is acceptable.

21 Bell 407GXi – Air Conditioning is not specified. Do you desire Air Conditioning? Air Conditioning is desired. B6.13.2 has been added to the solicitation.

Bell 407GXi; B6.21 – FLIR Talon MMS. Bell Textron Inc has not installed a FLIR Talon MMS sensor on a commercial aircraft and the Engineering will significantly increase cost. By using the FLIR 380-HDc on both the 407 and 412’s it provides redundancy between all 3 aircraft and benefits crew familiarization. Is this acceptable?

B6.21 has been updated.
