Rule 61.751 Eligibility Requirements

Training course

Rule 61.751 provides that to be eligible for a pilot chemical rating, a person must—

o hold at least a current private pilot licence in the appropriate category of aircraft; and

o have successfully completed a training course in agricultural chemical application, with assessment, conducted under the authority of a Part 137 agricultural aircraft operator certificate or a Part 141  aviation training organisation certificate.

Rule 61.753 Issue

Logbook endorsement

Rule 61.753 sets out  the requirements for the issue of a pilot chemical rating. The person  who completed the assessment must be satisfied that the eligibility requirements of rule 61.751 have been met before issuing the pilot chemical rating.

All relevant details must have been instructed, completed, and checked either orally, in writing, or in practice to the satisfaction of the certifying person who may issue the pilot a chemical rating by endorsing the applicant’s pilot logbook with the following statement in accordance with rule 61.29.

This is to certify that [name of pilot] has satisfied the requirements of Civil Aviation Rules Part 61 for the issue of a pilot chemical rating.

The holder of the pilot chemical rating may apply to the Director to have the rating endorsed on the holder’s pilot licence.

A pilot who holds a chemical rating granted under regulation 229 of the Civil Aviation Regulations 1953 is deemed to hold a chemical rating under Part 61 and thus eligible for endorsement of pilot’s logbook and pilot’s licence under rules 61.753(a) and (b).

Rule 61.755  Privileges

A current pilot chemical rating authorises the holder to dispense an agricultural chemical from an aircraft on an agricultural aircraft operation.

Rule 61.757  Currency Requirements

Refresher course

Rule 61.757 requires successful completion of a refresher course that is acceptable to the Director within the previous 5 years from the date of issue to be able to continue exercising the privileges of the rating, providing the certifying person has endorsed the holder’s pilot logbook in accordance with rule 61.29.

Currently the only courses acceptable to the Director, are conducted under the authority of a Part 141 aviation training organisation certificate.

A pilot who has completed a refresher course within 90 days before the expiry date is deemed to have completed the course on the required date.

Land Transport Rule: Dangerous Goods 2005

While Land Transport Rule for Dangerous Goods 2005 and storage of agrichemicals does not form part of Part 61 requirements, it does not however preclude course providers from providing guidance information or instruction or other regulations.
