Private company
Who owns Jet Parts Engineering ("JPE")
One company in the researched set discloses a stake in Jet Parts Engineering ("JPE"), none of it sized by anyone who discloses it. Jet Parts Engineering ("JPE") is private, so no 13F reports it: a 13F covers exchange listed positions only. These figures exist because each holder disclosed the stake in its own filings.

Jet Parts Engineering is a Seattle based designer and manufacturer of aftermarket parts and repairs for commercial aircraft. It develops proprietary alternatives to original equipment manufacturer components, approved under the Federal Aviation Administration's Parts Manufacturer Approval route, and sells them to commercial, regional and cargo airlines and to maintenance, repair and overhaul shops, with nearly all of its revenue coming from the commercial aftermarket rather than from new aircraft production. The company employs roughly 300 people and runs engineering and repair sites in Texas, New York, Florida, Alabama and the United Kingdom, covering a range of major commercial aerospace platforms. Together with Victor Sierra Aviation Holdings, a second aftermarket platform bought in the same transaction, it accounted for about 280 million dollars of revenue in calendar 2025.
Source
Jet Parts Engineering ("JPE") files nothing with the SEC, so none of this comes from a filer record. The description was written for this site in August 2026 from TransDigm Announces Acquisition of Jet Parts Engineering and Victor Sierra Aviation Holdings (PR Newswire, 16 January 2026), TransDigm Completes Acquisition of Jet Parts Engineering and Victor Sierra Aviation Holdings (PR Newswire, April 2026) and Jet Parts Engineering company website. The ownership figures below come from the holders' filings instead, and are sourced row by row.
The disclosed stakes
One row per position. Where a holder reports the same company in two share classes, both rows are shown rather than summed, because the class is part of a position's identity.
Where each figure comes from
A private stake has no ownership form behind it, so the source is always the holder's own filing or disclosure. Anything modelled says so, with the arithmetic.
- TransDigm Group Incorporated, as of 7 Apr 2026. This is the Nucor/Moody's ICRA precedent case the brief flags: TransDigm CONSOLIDATES JPE but does not wholly own it, so the majority stake is a real holding rather than an excluded wholly-owned subsidiary. On 7 Apr 2026, TransDigm completed the acquisition of approximately 95% of JPE's outstanding stock and approximately 96% of Victor Sierra Aviation Holdings (VSA, the other row here) in one combined transaction for approximately 2,200 million dollars in cash (definitive agreement signed 13 Jan 2026). The 10-Q discloses the ownership percentages for JPE and VSA individually and precisely, but discloses only the COMBINED purchase price and a COMBINED redeemable noncontrolling interest balance of 81 million dollars at 27 Jun 2026 (the fair value of the remaining minority stakes, i.e. the 5% JPE and 4% VSA held by management, not TransDigm's own majority stake). Because the dollar figures are not split between the two targets, value_usd is left null on both rows per the brief's combined-balance rule, and the combined figures are recorded here rather than assigned to one investee. source
What this page is not
It is not a complete register. It lists the holders who happen to be inside the researched set and disclosed the stake themselves. A private company can have many other shareholders, and nothing here rules them out: venture investors, founders and employees usually appear in no public filing at all. Percentages are of Jet Parts Engineering ("JPE") where a holder stated one, and are missing where no holder did.
