How do aircraft get STC?
An STC applicant submits a certification plan to the FAA that details the proposed alteration to a type-certified product and how that alteration will comply with the applicable FAA regulations and guidance material. The FAA reviews the certification plan and issues an STC project number if the plan is accepted.
What is a STC EASA?
Supplemental Type Certificates ( STC ) | EASA.
How do you calculate STC?
STC is calculated by taking the Transmission Loss (TL) values tested at 16 standard frequencies over the range of 125 Hz to 4000 Hz and plotted on a graph. Your curve (what you actually measured) is compared to standard STC reference curves (see appendix).
What are the STC holder responsibilities?
Make the type certificate available to FAA and National Transportation Safety Board, upon request (14 CFR § 21.49) Make Instructions for Continued Airworthiness available to owner/operator (14 CFR § 21.50) Make required design changes to address Airworthiness Directives and make them available (14 CFR § 21.99)
Is an STC approved data?
Approved data includes: Type certificate data and specification sheets, supplemental type certificates ( STC ), Airworthiness Directives (AD), manufacturer’s FAA approved data under a DOA, FAA Designated Engineering Representative (DER) data, FAA Designated Alteration Station (DAS) data and appliance manufacturers’
What is type certificate in aviation?
Type certification is the approval of the design of the aircraft and all component parts (including propellers, engines, control stations, etc.). It signifies the design is in compliance with applicable airworthiness, noise, fuel venting, and exhaust emissions standards.
What is the difference between Type Certificate and Supplemental Type Certificate?
A supplemental type certificate (STC) is a type certificate (TC) issued when an applicant has received FAA approval to modify an aircraft from its original design. A type certificate (TC) is issued to a new aircraft type and can only be applied for and issued to the manufacturer of that aircraft.
What does STC 45 mean?
Share. A sound blocking level of STC 45 means that a listener in a quiet room would hear raised speech in adjacent rooms, but would not be able to understand the conversation. The transmitted noise would not typically be disruptive.
How many STCs is a 5kW?
If you buy a 5 kW system in Melbourne, Victoria in 2019 the calculator will tell you that you are eligible for 71 STCs. You then multiply this by the dollar value of an STC in the market (your solar installer will be able to tell you the current value).
Is higher STC rating better?
Higher STC ratings generally are better. This means that extremely low frequencies don’t register on the STC rating scale, thus when a sound on one side of a wall is below 125Hz, the ability of the wall to block sound cannot be calculated. STC is not a direct measure of how many decibels of sound a wall can stop.
What is a Form 337?
The person who performs or supervises a major repair or major alteration must prepare FAA Form 337. The form is executed at least in duplicate and is used to record major repairs and major alterations made to an aircraft, airframe, powerplant, propeller, appliance, or a component part thereof.
What is the purpose of a Supplemental Type Certificate STC )?
A supplemental type certificate ( STC ) is a type certificate ( TC ) issued when an applicant has received FAA approval to modify an aeronautical product from its original design.
What is Type Certificate Data Sheet?
A TCDS is an FAA document that records the type certification data of a product (such as control surface movement limits, operating limitations, placards, and weight and balance) that may also be available in the flight manual or maintenance manual in accordance with FAA Order 8110.4.
