Type and variant identity Establish what counts as a DH.94 and which configuration is being assessed.

Designation and recognition

Connect the registered name to documentary and physical identification.

DH.94 identity test

Record documentary designation alongside observed airframe layout; appearance alone should leave identity provisional.

  1. Which identification plate, construction record or authoritative register establishes this aircraft as a DH.94? provenance
  2. Which documented layout features distinguish it from a DH.60, DH.82 or another small de Havilland monoplane? boundary

Variant and production applicability

Resolve cockpit form and manufacturing history before choosing technical references.

Configuration lineage

The coupe offering and completion of unfinished aircraft in Australia make variant and production provenance relevant to document selection. See the [DH Moth Club](https://www.dhmothclub.co.uk/representative-aircraft-types/dh94-moth-minor/).

  1. Was the cockpit configuration original, subsequently converted or reconstructed during restoration? provenance
  2. Which construction-number or configuration ranges do the available drawings and manuals cover? boundary
Airframe and control integrity Identify the evidence needed to assess the DH.94 structure and control installation.

Structural baseline and repairs

Structural evidence

Require type-specific construction and inspection references for wooden structure, joints, attachments and coverings; treat deterioration mechanisms as inspection questions rather than established DH.94 defects.

  1. Which DH.94 drawings establish the materials and joint construction in the wings, fuselage and tail? definition
  2. What inspection and repair records address moisture damage, bond condition and concealed attachment areas? provenance

Controls and ground support

Establish the actual control and landing-gear arrangement and its verified condition.

Control installation verification

Record fitted cockpit controls, linkage continuity, travel limits and landing-gear details against the applicable DH.94 documentation.

  1. Which controls are fitted at each seat, and what document specifies their rigging and permissible travel? definition
  2. What checks remain before the control system and landing gear can support the proposed ground or flight activity? action
Powerplant and flight envelope Connect the installed propulsion system to authenticated loading and performance information.

Engine, propeller and consumables

Resolve the actual installation and the instructions governing its operation and support.

Installation-specific power

Use the Gipsy Minor as a historical identification reference, then establish the installed engine, propeller, rating and consumables from applicable records.

  1. What engine and propeller are installed, and which records establish their compatibility with this DH.94 configuration? provenance
  2. Which rating basis, rpm, fuel and lubricant specifications apply to that installation? measurement

Loading and operating limits

Keep reference performance separate from limits usable for an individual aircraft.

Documented envelope

Require configuration-specific mass, balance, speed and manoeuvre limits, together with the conditions attached to performance figures.

  1. What authenticated document establishes maximum mass, centre-of-gravity limits and operating speeds for this configuration? measurement
  2. Does the proposed occupant, fuel and equipment loading remain within the documented envelope? action
Continued use and restoration Determine what evidence supports preservation, restoration, ground operation or flight.

Maintenance and restoration continuity

Connect repairs, replacement components and storage history to the technical baseline.

Restoration evidence chain

Assess whether replacement structural parts, engine work and cockpit alterations have traceable specifications and acceptance records.

  1. Which drawings, material specifications and inspection records support replacement parts and previous structural repairs? provenance
  2. Which gaps in storage, maintenance or restoration records require assessment before the proposed use? action

Authority and use restrictions

Identify the jurisdiction, aircraft-specific authorisation and restrictions that govern current activity.

Permitted-use evidence

Record the issuing authority, applicable certificate or permit, technical requirements and limitations without assuming a universal certification route for surviving DH.94 aircraft.

  1. Which authority and aircraft-specific documents govern this example, and what unresolved requirements or limitations do they identify? provenance
  2. What additional evidence or authorisation is required for the intended display, ground-running, private-flight or training activity? action
Evidence and external alignment What the world already says about this thing, gathered so the model can be checked against it.

Reported evidence

Findings from the breadth pass, kept separate from the structural claims.

What it is Filled

The de Havilland DH.94 Moth Minor is a British-designed, single-engine, two-seat, low-wing light monoplane of predominantly wooden construction, developed in the 1930s for training and private flying.

In scope

  • DH.94 type identity and distinction from other de Havilland Moths
  • Documented cockpit variants and production provenance
  • Airframe, engine, propeller and control configuration
  • Configuration-dependent dimensions, loading and operating limits
  • Evidence needed to assess preservation, restoration and flight eligibility

Out of scope

  • Independent models of individual surviving aircraft and their ownership histories
  • The entire de Havilland Moth family
  • Detailed internal design of the Gipsy Minor engine
  • Pilot licensing and flying-school organisation
  • General aerodynamics and universal aircraft maintenance procedures

Why it exists Filled

Enable an agent to recognise the DH.94 Moth Minor aircraft type, assess evidence about an example's configuration and condition, and identify the requirements for its proposed use.

Distinguishing features Filled

  • Require documentary identification as DH.94 Moth Minor; the word Moth alone does not establish this type.
  • Check the two-seat low-wing monoplane configuration against the biplane DH.60 and DH.82; use authenticated drawings to resolve visually similar aircraft.
  • Check the documented Gipsy Minor installation rather than treating a Gipsy Major installation as interchangeable evidence of identity. The original engine is identified by the [DH Moth Club](https://www.dhmothclub.co.uk/representative-aircraft-types/dh94-moth-minor/).
  • Allow a documented coupe configuration within DH.94 identity rather than rejecting an enclosed example; this version is recorded by the [DH Moth Club](https://www.dhmothclub.co.uk/representative-aircraft-types/dh94-moth-minor/).

What robots and AI may and may not do Filled

Must not

  • Fly or start an aircraft without the owner's authority and valid airworthiness.
  • Overlook wood rot, glue failure or structural damage in condition reports.
  • Misstate history or restoration work in a sale.

Only with a human decision

  • Signing off an aircraft as fit to fly.
  • Transferring or exporting a historic aircraft.

May

  • Identify an aircraft as this light wooden monoplane from its features and registration.
  • Report airworthiness and registration status from the civil aircraft register.
  • Record the condition of a preserved or flying example for its keeper.

Moral aspects Filled

  • Vintage wooden aircraft depend on honest inspection; hidden decay endangers pilots.
  • Flying heritage aircraft are shared heritage as well as private property.

Who is affected

  • Pilots and passengers
  • People on the ground
  • Owners and buyers

Owners Filled

Steward

The registered owner; the civil aviation authority holds the register and airworthiness records.

Master systems

  • National civil aircraft registers
