Every prompt we use, published.

Words

• Rule 1.1 · error "Prior to starting this procedure" — "Prior to" is not an approved STE word.
• Rule 1.1 · error "Utilize the special tool" — "Utilize" is not an approved STE word.
• Rule 1.14 · error "depressurised" — British spelling. American form: depressurized.
• Rule 1.14 · error "stabiliser" — British spelling. American form: stabilizer.

Multi-word nouns

• Rule 2.1 · warning "forward equipment bay distribution panel isolation switch" — A seven-word unbroken noun string against the three-word limit. Restructure with prepositions rather than stacking the nouns.

Verbs

• Rule 3.2 · error "has been depressurised" — Present perfect. Use the simple past or imperative.
• Rule 3.4 · error "has been depressurised" — Auxiliary plus past participle forming a disallowed complex construction.
• Rule 3.2 · error "has been disconnected" — Present perfect. Use the simple past or imperative.
• Rule 3.4 · error "has been disconnected" — Auxiliary plus past participle forming a disallowed complex construction.
• Rule 3.6 · error "make sure that the hydraulic system has been depressurised and that the electrical supply to the forward equipment bay distribution panel isolation switch has been disconnected" — Passive rather than active. Procedural writing must always use the active voice.
• Rule 3.6 · error "The stabiliser trim actuator is installed in the forward bay." — "is installed" reads as a passive construction. Rewrite in the active voice.

Sentences

• Rule 4.2 · error "Don't remove it." — Contraction. Write the full two-word form.

Procedural writing

• Rule 5.1 · error "Prior to starting this procedure, make sure that the hydraulic system has been depressurised and that the electrical supply to the forward equipment bay distribution panel isolation switch has been disconnected." — 31 words against the 20-word procedural limit. Split into shorter steps.
• Rule 5.2 · error "Utilize the special tool to release the retaining collar; then remove the access panel." — Two sequential instructions in one sentence. The actions do not happen at the same time, so they belong in separate numbered steps.
• Rule 5.3 · error "make sure that the hydraulic system has been depressurised and that the electrical supply ... has been disconnected" — Not written as a direct command. Procedural instructions take the imperative form.

Descriptive writing

• Rule 6.3 · error "The forward equipment bay is a compartment which contains the primary hydraulic distribution components and the associated electrical isolation equipment, and access to it is obtained through a panel on the lower fuselage which is secured by twelve quick-release fasteners." — 40 words against the 25-word descriptive limit. Split into shorter sentences.
• Rule 6.1 · warning "The forward equipment bay is a compartment which contains the primary hydraulic distribution components and the associated electrical isolation equipment, and access to it is obtained through a panel on the lower fuselage which is secured by twelve quick-release fasteners." — Two subjects in one sentence: what the bay contains, and how it is accessed. Give each its own sentence.

Safety instructions

• Rule 7.3 · warning · needs review "WARNING: Do not touch the actuator housing." — No explanation of the risk or the result of not obeying. Flagged as needing review, not as an automatic error.

Punctuation and word count

• Rule 8.1 · error "Utilize the special tool to release the retaining collar; then remove the access panel." — The semicolon is prohibited outright. Write two sentences instead.

Writing practices

• Rule 9.4 · warning "forward equipment bay" — Named two ways in this passage: "forward equipment bay" and "forward bay". Use one term throughout.

A deviation the pass missed

"Follow the torque values given in the maintenance manual."

"Follow" is approved, so the dictionary lookup passes it, and P1’s check phase reports nothing on this sentence. The deviation is real: STE approves "follow" only with the meaning "come after, go after", and the approved word for complying with an instruction is "obey". The lookup is evidence a word is on the list, never a verdict that its use here is correct — this is the single clearest illustration of why.

A finding the pass reported that is wrong

"The stabiliser trim actuator is installed in the forward bay."

"is installed" describes a state, not an action someone performs, so rule 3.3 governs and the construction is compliant. A model reading "is" plus a past participle frequently reports it as a rule 3.6 passive-voice violation instead, which is exactly the ste-execution-spec.json crossRulePrecedence conflict between rules 3.3, 3.4 and 3.6. The sentence does carry a real, separate deviation — "stabiliser" under rule 1.14 — so the honest picture is one true finding and one false one in the same sentence.
