Neonatal Transportation Unit Modification on Bell 430 and TC 695
Summary: Reduced the weight of a hospital’s neonatal incubator transportation unit, lessened electrical power usage, and provided STCs for change in type design for Bell 430 Helicopter and Twin Commander 695 Airplane.
Project Name: Neonatal Transportation Unit Modification
Client: Emanuel Children’s Hospital of Portland, Oregon
Client Request: To reduce the overall assembly weight of the hospital’s neonatal transportation unit for a Bell 430 Helicopter and a Twin Commander 695 airplane.
Project Summary: Emanuel Children’s Hospital of Portland, Oregon, transports critically ill neonatal infants with their Bell 430 helicopter and Twin Commander 695 airplane in an incubator that attaches to a Lifeport, Incorporated click deck litter. Several staff members have suffered workplace back injuries as a result of the excessive weight of the entire assembly. The hospital asked Fliegen Works to modify the design to reduce the overall weight of the assembly and to get the system approved for operation in the Bell 430 helicopter.
Results: Fliegen Works replaced the oxygen shroud with mounted ventilator, patient monitor, and two E cylinders of the Lifeport ITM with lighter weight equipment. The new medical cylinder shroud houses two cylinders, has a new Broncotron mechanical high frequency ventilator, and new Crossvent regular ventilator with monitoring functions. The ProPaq patient monitor mounts to the new shroud with a lighter attachment. In addition to lightening the assembly, the ventilators use less electrical power than the original ventilators.
FAA Approvals: STC for change in type design for a Bell 430 Helicopter (ST02257AK) and a Twin Commander 695 Airplane (SA01620SE).
CASA C-212 Combi Cargo Conversion
Summary: Conversion of a CASA C-212 from the passenger only configuration, to a combined passenger and cargo configuration (Combi).
Project Name: CASA C-212 Combi Conversion
Client: FS Air Service
Client Request: Get an STC to modify the CASA C212 for carrying cargo with passengers in the same cabin with multiple configurations.
Project Summary: Fliegen Works Inc. provided a certification plan, compliance checklist, structural substantiation, smoke testing, and DER services in support of an STC project to convert the CASA C-212 aircraft from the original passenger-only or cargo only configurations to a combined passenger and cargo configuration. The project included a novel approach of using fire containment blankets to segregate the cargo within the passenger compartment using data from the FAA tech center. This project required the design and installation of new emergency equipment for installation in the cabin as well as a thorough Aircraft Flight Manual Supplement (AFMS). Fliegen Works coordinated with the FAA to grant an Exemption to allow the use of building type smoke detectors for fire detection within the fire containment blankets. This project culminated in TIA for demonstration of smoke detection per 25.857 and ventilation per 25.831. Fliegen Works built a smoke box per AC 25-9A appendix II, which generates a precise amount of smoke and is available for other projects.
Results: STC ST02257AK approved for change in type design.
