Design
The Bell 412EPI offers a rugged airframe built with safety in mind, as well as upgraded engines that provide 15 percent more horsepower than the Bell 412EP. Fabric covered high-backed folding seats with individual seat belts and single strap shoulder harness and inertia reel, arranged with one row of four (two 2-place benches) forward facing seats, and one row of five forward facing seats, and two outward facing two place benches (one on either side of the transmission). Available with Grey, Blue, Red, or Tan upholstery with Black seat belts. Seats are are also available in all vinyl at additional cost. (214.5 lb [97.3 kg] included in the standard configuration weight.)
Utility Seating - Available for U. S. registered helicopters ONLY with addition of STC Alpine Bell 412 Passenger Shoulder Harness Kit. Nylon covered bench type seating arranged with one row of four rearward facing seats (behind the crew seats), one row of five forward facing seats (in front of the transmission), and two outward facing two place benches (one on either side of the transmission). Each seat has an individual seat belt. Available in Tan or Black. The Utility Seating decreases the standard configuration weight (-95.7 lb [-43.4 kg], with Alpine STC Shoulder Harness -61.4 lb [-27.9 kg]).
The Standard Interior Trim is provided as a NO COST OPTION, but is not included in the Standard Configuration Empty Weight. Included are: Plastic closeouts on upper sidewalls,window reveals, and cabin headliner; Padded vinyl covering the floor and lower door panels; Lower aft bulkhead covered with padded vinyl blankets. The hard plastic headliner and closeouts are off-white in color, and the padded bulkhead blankets and floor covering are color coordinated to match the seat color selection. The Standard Interior Trim increases the standard configuration empty weight (165.7 lb [75.2 kg]).
Utility Interior Trim – The Utility Interior Trim consists of: Light beige vinyl covered headliner and bulkhead blankets; Doors painted light beige; Floor painted brown. The Utility Interior Trim is included in the standard configuration empty weight (33.3 lb [15.1 kg]).
Avionics and equipment
The standard configuration of the Bell 412EPI provides single-pilot or dual-pilot IFR capability with 3-axis stability augmentation (SAS) and a coupled flight director capability. All Engine Indication and Crew Alerting System (EICAS) display functions are provided through the Bell BasiX-Pro™ Avionics System. The system works in conjunction with the engine control units (EEC/ECUs) for the Pratt & Whitney electronically-controlled PT6T-9 Twin Pac® engines. Other aircraft systems indications, warnings, cautions, aural alerts, and automated performance features are provided through the remotely located Aircraft Data Interface Unit (ADIU). Power and performance situational awareness is enhanced through Bell Helicopter’s patented “PSI” presentation. The PSI (Power Situation Indicator) provides a single gauge to monitor use of engine power relative to multiple limits simultaneously, and assures maximum power usage and workload reduction in OEI as operation transitions to flying RPM indication against the engine limiters. Systems monitoring workload is reduced through EICAS design for rapid scanning. Display-by-exception, normalized scales, subdued red and yellow markings except in appropriate conditions: These all contribute to reduced pilot instrument scan times through an effective EICAS design made specifically for the demands of helicopter use.
The 412EPI STC replaces COM1, NAV1, and the transponder from the original Bell 412EP with a helicopter approved Garmin GTN-750 NAV/COM/WAAS GPS and a GTX-33EH ES remote transponder. The GTN-750 provides a high-resolution touch-screen display with extensive digital mapping capability, terrain presentation, electronic charts and approach plates. The GTN-750 also provides the control interface for the GTX-33EH ES. The Garmin GTX-33EH ES is an ELS-compliant, Mode S transponder with 1090MHz extended squitter ADS-B reporting capability. A Garmin GNS-530AW can be optionally configured in place of the GTN-750, in this case the existing MST-67A transponder is maintained. Both the GTN-750 or GNS-530AW configurations support LPV (Localizer Precision with Vertical guidance) coupled approaches through the BasiX-ProTM system. The Bell 412EPI also incorporates a KRA-405B radar altimeter as part of the basic equipment.
Bell 412EPI retains the existing NAV2 (KNR-634A VOR/ILS/MB), COM2 (KTR-908), DME (KDM-706A) and ADF (KDF-806) from the Bell 412EP IFR configuration. The Audio/Intercom Panel provided in later variant Bell 412EP aircraft (NAT N301A) is compatible with the improved audio and voice alerting provided by the Bell BasiX-ProTM system. Otherwise any installed /approved audio system with a compatible direct un-switched input can be used. Prior intercom systems (P/N 212-077-200) are not compatible. Standard installation of the NAT N301A is for high impedance headsets but the units can be alternately wired for low impedance (military style) headsets.
Propulsion
Bell 412EPI incorporates the power of Pratt & Whitney's PT6T-9 Twin Pac® engines and the BLR Strake and FastFin System, which improve hot and high performance by as much as 1,410 pounds of payload capacity.
Operation
The Bell 412EPI is a workhorse for everything from law enforcement to oil and gas transport, ideal for any mission requiring power and performance.
