ECCN 9D004
NSATOther software as follows .
What This ECCN Covers
ECCN 9D004 controls specific aerospace "software" enumerated in the entry — for example certain engine-control (FADEC) and aerodynamic-modeling software defined in its sub-paragraphs. It is controlled for National Security and Anti-Terrorism reasons, with scope set by the items the List of Items Controlled names.
Who needs to check this?
Developers of engine-control, flight-modeling, and related aerospace software, and the OEMs that integrate it.
Compliance tip
Read the List of Items Controlled closely — 9D004 is itemized, so map your software to the specific sub-paragraph. Verify the §734.7 "published" exclusion for publicly available code, and confirm the NS and AT Country Chart columns.
Items Covered
- b."Software" for testing aero gas turbine engines, assemblies, "parts" or "components", having all of the following:
- 1. specially designed for testing any of the following:
- 1.a. Aero gas turbine engines, assemblies or components, incorporating "technology" specified by 9E003.a, 9E003.h or 9E003.i; or
- 1.b. Multi-stage compressors providing either bypass or core flow, specially designed for aero gas turbine engines incorporating "technology" specified by 9E003.a or 9E003.h; and
- 2. specially designed for all of the following:
- 2.a. Acquisition and processing of data, in real time; and
- 2.b. Feedback control of the test article or test conditions (e.g., temperature, pressure, flow rate) while the test is in progress;
- c."Software" specially designed to control directional solidification or single crystal material growth in equipment specified by 9B001.a or 9B001.c;
- e."Software" specially designed or modified for the operation of items specified by 9A012;
- f."Software" specially designed to design the internal cooling passages of aero gas turbine engine blades, vanes and "tip shrouds";
- g."Software" having all of the following:
- 1. specially designed to predict aero thermal, aeromechanical and combustion conditions in aero gas turbine engines; and
- 2. Theoretical modeling predictions of the aero thermal, aeromechanical and combustion conditions, which have been validated with actual turbine engine (experimental or production) performance data.
