1. BACKGROUND:

Under the authority of Title I, Sec. 101 Homeland Security Act of 2002 as amended, the Department of Homeland Security (DHS) was established to prevent terrorist attacks within the United States; reduce the vulnerability of the United States to terrorism; and minimize the damage, and assist in the recovery, from terrorist attacks that occur within the United States.

AMO is steadfast in its commitment to provide the safest Helicopter Flight Helmet available on open source to their crew members that incorporates the latest technological advancements in comfort and communications. This helicopter flight helmet will serve as a regulatory piece of Aviation Life Support Equipment (ALSE) as well as the means to communicate and mount Night Vision Goggle (NVG) devices. The requirements will facilitate effective communication with air traffic control facilities and other aircraft as well as with individuals encountered once dismounted from the aircraft during instances where it would not be prudent to remove the helicopter flight helmet.

The following mission sets illustrate why such a flight helmet is a crucial component in AMO’s successful execution of priority Department of Homeland Security (DHS) and CBP missions:

Air to Land Enforcement – The capability to search, detect, identify and track suspect ground targets of interest moving by vehicle or on foot. Interdiction can occur on approach to the land border, at crossing points or after the border has been breached. Air to land interdiction is conducted in all geographic conditions and at all borders.

Air to Air Enforcement – The capability to search, detect, track and sort airborne suspect targets of primarily general aviation aircraft. In a national security role, this serves the function of determining hostile intent of the suspect aircraft. Air interdiction is conducted over both land and sea in all weather conditions and operating environments. The mission includes an apprehension capability far before a suspect air target approaches the border, as the border is crossed and well into interior airspace.

Critical Infrastructure and Port Security – The capability to detect, deter and prevent terrorist attacks on critical infrastructure and at U.S. ports of entry. This includes the tracking of possible terrorist threats as they approach the border, apprehension of suspect targets and monitoring of border areas through air and marine tactical and strategic assets. In addition to these duties, OAM assets provide security and surveillance at special events.

2. SCOPE:

This Statement of Work (SOW) defines the minimum physical, functional and technical requirements for a helicopter flight helmet. AMO’s objective is to provide each DHS/CBP AMO pilot/air crew member a helicopter flight helmet (sand colored, gloss finish) from an authorized Continental United States (CONUS) helmet distributor. The selected helicopter flight helmet will enhance our agents’ situational awareness and ability to complete their respective missions utilizing, what AMO requires, an apparatus that provides unparalleled safety and communication performance.

AMO’s helicopter flight helmet stock is critically low due to previously issued flight helmets nearing the end of their expected life cycle, requiring replacement during semiannual safety inspections, coupled with the initially issued flight helmets to recent graduates from our DHS/CBP AMO Academy classes. The projected number of pilots/air crew members graduating from our remaining DHS/CBP OAM FY20 Academy classes exceed the number of helicopter flight helmets that we currently have in stock.

3. APPLICABLE DOCUMENTS:

Commercial standards shall be used wherever practicable.

4. SPECIFIC TASKS:

The contractor shall provide all the items as specified in this Statement of Work (SOW).

The following sections outline the respective physical, functional and technical characteristics of the helicopter flight helmet. The CONUS helmet distributor shall be responsible for providing units meeting these characteristics. This is considered a non-developmental effort and Commercial Off The Shelf (COTS) solution is being sought.

Tasks include but are not limited to design, manufacture, fabrication, safety performance results, procurement, integration, initial sizing, fit and maintenance training and helicopter flight helmet support that meets CBP, AMO requirements, as listed in their respective sections.

4.1 MINIMUM EQUIPMENT

The helmet shall include the following features:

· Dual lenses with clear inner lens and dark outer lens

· Electret microphone with cord, boom, and mount

· Face shield attachment hardware

· ANVIS Night Vision Quick Disconnect

· Helmet liner

4.2 SIZES

The helmet must be available in at least six sizes utilizing at least four shell sizes to ensure that helmets fit a wide range of head sizes using shell sizes that are proportional to the head size.

4.3 IMPACT PROTECTION

The Helmet Assembly with Dual Visor Assembly shall limit peak head form deceleration to 150 g in the crown and 175 g in the headband area when subjected to impact velocities of 4.88 m/sec and 6.0 m/sec respectively.

Helmet impact tests shall be performed in accordance with the impact test method specified in American National Standards Institute (ANSI) Z90.1-1979 with the following exceptions:

1. Impact shall be single impacts only.

2. Drop velocity to be:

a. Crown area = 4.88 m/sec

b. Headband area = 6.00 m/sec

3. Department of Transportation B, C, & D head forms will be used for appropriate size helmets. The drop assembly weight can be 10.1 lbs. for the B size head form in lieu of 8.9 lbs. as specified in DOT 218 (10-1-78).

4. Impacts will be tested at high temperature and ambient temperatures only. The crown and headband area will be defined as shown in Figure 1. Test equipment set-up will be as shown in Figure 2. All Figures are located in section 10.

Testing shall begin immediately after removal from the conditioning equipment. For any environmental tests, the helmet assembly shall not be out of the conditioned environment for more than five (5) minutes. If testing exceeds this time limit, the helmet assembly shall be returned to the conditioning environment for a minimum of 15 minutes before being withdrawn.

The test helmet shall be tested with the appropriate size liner fitted to the head form.

The entire test system shall be calibrated before and after each series of tests by impacting a standardized calibrating medium utilizing an appropriate drop height. At least three such impacts shall be recorded before and after testing. If the post-test average of the three impacts differs from the pre-test average by more than 10%, the entire test series must be considered void and repeated.

Additionally, a velocity reading shall be taken at impact from the calculated drop height to determine if adjustments must be made to the drop height to obtain the required impact velocity (compensation for tower drag).

The impact helmet shall be custom fit to the test head form to ensure a firm fit of the helmet to the head form at the target areas.

The test unit shall be affixed to the test head form so that the Forehead Reference Point (FRP) is 2.125 inches above and parallel to the basic plane of the test head form.

Crown area peak deceleration = 150 g Drop velocity = 4.88 m/sec

Headband area peak deceleration = 175 g Drop velocity = 6.0 m/sec

The helmet shall be secured to the head form and support arm by its retention system (chinstrap and nape strap) so as to maintain the Forehead Reference Point (FRP) at a point 2.125 inches above and parallel to the basic plane of the test head form

The offset distance between the outside of the helmet and the head form shall be measured at each impact site. The offset distance is the distance between the outer shell surface of the helmet and the head form’s surface. To determine this distance:

1. Measure the distance from the fixture base to the anvil.

2. Place the helmet assembly onto the head form so that the Forehead Reference Point (FRP) is 2.125 inches above and parallel to the basic plane of the test head form. Lower the helmeted head form onto the flat anvil and re-measure the distance from the fixture base to the flat anvil. This is the offset position.

3. The offset distance shall be obtained by subtracting the zero position from the offset position (step b from step a).

The head form shall be rotated to another impact site after each impact site had been impacted. These steps are then repeated for each of the remaining impact sites.

Two helmets shall be used for impact testing. One helmet shall be used to impact the crown, front and rear impact sites, and the second helmet shall be used to impact the crown and left and right impact sites.

The above described testing was conducted and the Helmet passed all required criteria prior to the original purchase of these helmets in 2015.

4.4 EAR IMPACT PROTECTION

When tested in accordance with this section, the Helmet Assembly (with Dual Visor Assembly) shall limit peak head form deceleration to 150 g when subjected to an impact velocity of 6.0 m/sec in the earcup area.

The impact attenuating capability of the earcup area of the helmet subassembly shall be tested in a similar manner to the basic shell and liner structure stated in the section titled “IMPACT PROTECTION” with the following exceptions:

a. A modified ANSI size "C" head form as detailed in Figures 3 and 4 is to be used. This head form is identical to the existing size "C" ANSI model with the exception that the ear region has been extended downward 2.8 cm in the ear region as shown. The drop assembly weight shall be 5.2 kg.

b. The appropriate size helmet shall be fitted to the modified "C" head form so that the helmet is centered laterally on the head form, i.e., the earcups shall be fitted with an equal number of fitting pads on each side. The number of fitting pads will be such that a uniform and approximately 50 percent compression of the earseal results on each side more nearly simulating the as worn condition.

c. The earcups shall be located as for normal wear in the helmet, but care shall be exercised to place their centroid at the asterisk location shown in Figure 3.

d. The head form point of impact (asterisk of Figure 3) shall be positioned as shown to be tangent to the flat anvil.

e. The earphones shall be included in the test item configuration.

f. The drop velocity shall be 6.0 m/s.

g. The peak head form deceleration shall not exceed 175 G's.

h. Impact testing to be performed at ambient conditions only.

4.5 SHELL PENETRATION RESISTANCE

A helmet shell tear penetration test shall be performed in accordance with the following procedure. The impactor drop mass is 5.0 ± 0.1 kg and the drop height is 1.52 ± 0.05 meters. The maximum helmet shell tear length shall be 5 cm. Tear length which exceeds 5 cm shall be cause for rejection. The impactor shall be fabricated as shown in Figure 5 and Figure 6 and utilized on an appropriate drop test fixture.

4.6 ACOUSTIC ATTENUATION

When tested in accordance with American National Standard Institute (ANSI) Method S12.6-1984, or MIL-STD-912, the Helmet Assembly shall meet the minimum attenuation requirements of Table 1.
