P2F conversion STCs for the certification data spine of a freighter conversion

What gets reviewed

• Trace conversion STC and AML applicability to the donor aircraft's exact configuration against the claim it supports.
• Challenge structural substantiation for the main-deck floor and cargo door against the claim it supports.
• Reconcile cargo compartment classification and smoke detection evidence against the claim it supports.
• Confirm 9g barrier data against the claim it supports.
• Index supplemental ICA against the claim it supports.
• Compare AFM supplement against the claim it supports.

What gets validated

• Limit carryover: conversion STC and AML applicability to the donor aircraft's exact configuration fails review if the cited record cannot be tied to the current baseline.
• Source control: structural substantiation for the main-deck floor and cargo door fails review if the cited record cannot be tied to the current baseline.
• Closure owner: cargo compartment classification and smoke detection evidence fails review if the cited record cannot be tied to the current baseline.
• Configuration match: 9g barrier data fails review if the cited record cannot be tied to the current baseline.
• The review notes that evidence link: supplemental ICA fails review if the cited record cannot be tied to the current baseline.

Evidence normally required

• Analysis note: conversion STC and AML applicability to the donor aircraft's exact configuration
• Manual source: structural substantiation for the main-deck floor and cargo door
• Configuration item: cargo compartment classification and smoke detection evidence
• Closure evidence: 9g barrier data
• Baseline record: supplemental ICA
• Test file: AFM supplement

Common discrepancies

• Buyer concern: a donor aircraft whose configuration falls outside the substantiated baseline.
• Program risk: missing loading system substantiation blocking cargo operations approval.
• Authority question: records split between converter and operator at redelivery.
• Finding in records: baseline does not match the delivered records.

How the work runs

• Applicability and approval basis summary
• Source record request list

Who uses the output

• Asset managers use the map to brief the decision.
• Technical diligence advisors use the register to assign closure.
• Conversion program managers use the request list to collect source records.

How the work fits into the transaction or program

The decision is what the certification data package of a passenger-to-freighter conversion contains and what operators, lessors, and investors should verify in it before committing an airframe. The evidence set centers on the conversion STC and AML applicability to the donor aircraft's exact configuration, structural substantiation for the main-deck floor and cargo door, cargo compartment classification and smoke detection evidence, the 9g barrier data, and the supplemental ICA, AFM supplement, weight and balance, and. The likely weak points are a donor aircraft whose configuration falls outside the substantiated baseline, missing loading system substantiation blocking cargo operations approval, and records split between converter and operator at redelivery. The output gives the asset manager a cleanup register for P2F conversion STCs for the certification data spine of a freighter conversion before freighter conversion decision or converted-asset acquisition.

Regulatory limits

EE does not certify equipment, approve installations, or declare an aircraft compliant. The output identifies supportable claims, missing records, and questions that need applicant or authority disposition.

Specific to this review

• what the certification data package of a passenger-to-freighter conversion contains and what operators, lessors, and investors should verify in it before committing an airframe.
• Conversion STC and AML applicability to the donor aircraft's exact configuration often controls whether later summaries can be trusted.
• A donor aircraft whose configuration falls outside the substantiated baseline is treated as a record gap until an owner closes it.
• FAA and EASA evidence should stay distinguishable from commercial claims and installer notes.
• The scope uses the Passenger Freighter Conversion STC question as the control point, so the review stays tied to Freighter conversion decision or converted-asset acquisition and the buyer decision behind it.
• The evidence starts with Conversion STC and AML applicability to the donor aircraft's exact configuration and follows Support Certification Evidence P2f references until every exception has a source location and a reason code.
• The finding logic separates missing paperwork, conflicting status, stale revision data, and unsupported disposition because each class closes through a different owner.
• The timing matters for Asset manager: the output is useful only if the unresolved items are visible before acceptance, submittal, handback, or negotiation pressure fixes the sequence.
• The boundary control keeps Stcs Data Spine Cert questions in the records or certification lane and sends technical acceptance issues to the authorized people who own them.
• The handoff value comes from Evidence map for Passenger To Freighter Conversion STC; it gives the next reviewer a precise map instead of another broad request for a better file.
