The engines on both the Phenom 100 and 300 are built by Pratt & Whitney Canada. Phenom 100 is powered by the PW617F-E (1,695 lbf, 3,500 hours TBO) and Phenom 300 by the PW535E (3,360 lbf, 5,000 hours TBO).
The Engine Maintenance Manual, available via Embraer myTechCare, PWC, or your Maintenance Tracking provider outlines the inspection requirements.
The engines have a light inspection in conjunction with the airframe 12 Mo inspection.

The initial HSI for the PW535E series engines must be performed at 2500 flight hours. Subsequent HSIs must be done every 2500 flight hours. An additional 50 flight hours is available for scheduling purposes.
The initial HSI for the PW617F series engines must be performed at 1750 flight hours. Subsequent HSIs must be done every 1750 flight hours. An additional 50 flight hours is available for scheduling purposes.
Hot Sections are done on-wing, typically by a mobile PWC team unless you fly the plane to a PWC facility. ESP does not cover the travel expenses for scheduled maintenance, so expect ~$6000/engine.
If you don't have ESP, as of 2017 PW617F hot sections ran ~$115k per engine.
The TBO for the PW535E series engines is 5000 flight hours. An additional 100 flight hours is available for scheduling purposes.
The TBO for the PW617F series engines is 3500 flight hours. An additional 100 flight hours is available for scheduling purposes.
Further increases to the TBO interval are subject to the approval of the operator's local regulatory authority and it is the responsibility of individual operators to make applications for such increases. P&WC can provide an additional 100 operating hours (instead of 50 hours) to operators that need to schedule a HSI and an overhaul for two engines installed on the same aircraft.
On-wing Low Utilization Engine Inspection
A low utilization engine is defined as an engine that has not been subject to disassembly and inspection of both hot section and cold section at an approved overhaul facility by the end of:
PW617F 12 years since Entry Into Service/Overhaul or 13 years since engine manufacture (whichever comes first).
PW535E 10 years since Entry Into Service/Overhaul or 11 years since engine manufacture (whichever comes first).
An additional 1 month or 10 flight-hours, whichever comes first, is available for scheduling purposes.
Subsequent Low Utilization Inspections are to be performed every 24 month interval until overhaul.
