Beechcraft G58 Baron Model Guide
Beechcraft G58 Baron · Model Guide
Overview
The Beechcraft G58 Baron is a twin-engine piston airplane (category: twin-engine-piston) in the library from 2005, with no end year listed, so it is treated as still in production. It seats 4 to 6. The supplied documents contain no registry or performance figures for the Beechcraft G58 Baron, so this guide covers what the documents do support: V-speed markings from one STC supplement, service documents, gear-extension technique, avionics and a sample weight-and-balance record. It does not cover range, speed or payload. Get those from the G58 handbook for the specific airplane.
- The Beechcraft G58 Baron is a piston twin that seats 4 to 6. The inputs give no range, speed or payload numbers, so verify them in the airplane's own handbook.
- The only POH supplied is for Baron 58 and 58A serials TH-1 thru TH-772. It is not the G58 handbook, so confirm that the manual and supplements match the airplane's serial number.
- The landing gear is electric, not hydraulic. It will not free-fall, so a gear motor failure means hand-cranking the gear down.
- Check the service history. A recommended rudder cable pulley bracket bulletin covers G58 serials TH-2125 through TH-2136. A recommended nacelle keel rivet letter covers certain G58 serials from TH-2468 on.
- If the airplane has a vortex generator (V/G) kit, the supplement lists a lower Vmca of 74 KCAS. The kit needs its full set of generators in place.

Do the documents give range, cruise speed or payload for the Beechcraft G58 Baron?
No. The inputs contain no registry or performance figures for the Beechcraft G58 Baron, so none are stated here. Get them from the handbook for the specific airplane.
Does the Beechcraft G58 Baron have hydraulic landing gear?
Per the gear-extension article for Bonanza and Baron models, the gear is electrically driven with push rods and has nothing hydraulic. It will not free-fall if the motor fails, so the pilot must hand-crank it down. Practice this once with an instructor.
What does a vortex generator kit change on a Beechcraft G58 Baron?
The supplement for the Baron 58, 58A and G58 describes a kit of 107 vortex generators that lowers stall and Vmca speeds. It sets Vmca at 74 KCAS. If fewer than 107 are in place, the airplane must be operated per the original POH. The supplement also advises flying by the original POH performance figures for extra margin.
Are the weight-and-balance figures here for a G58?
No. The Beechcraft G58 Baron weight-and-balance document is a set of equipment-change records for a Model 58, serial TH-2103. It shows a 5500 lb gross weight and an empty weight of 4011.06 lb. Use those figures only as an example of the records to expect. For a G58, use that airplane's own current weight-and-balance data.

What the documents say about the airframe and equipment
The library lists the Beechcraft G58 Baron as a piston twin with 4 to 6 seats, first listed in 2005. A Garmin G1000 Pilot's Guide exists for the G58 (190-00629-04 Rev. A, software version 0857.10 or later), so a G1000 glass cockpit is part of the G58 documentation. Its warnings say not to use terrain displays as the sole source of terrain and obstacle separation. Verify that the installed avionics and software match the pilot's guide.
Service documents to check against the logbooks
SB 27-3789 (Dec 2006, recommended) inspects the rudder cable pulley bracket (P/N 002-440010-19) for elongated or misdrilled holes. It lists G58 serials TH-2125 through TH-2136 and should be done at the next scheduled inspection. Estimated time is 1.0 hours to inspect. If the pulley guard pin must be replaced, the estimate is 0.25 hours. Service Letter MEL-57-03 (Jan 9, 2020, recommended) inspects the outboard wing nacelle keels for missing rivets. It lists G58 serials TH-2468, TH-2472 thru TH-2516, TH-2519, TH-2520 and TH-2522. It should be done at the next 100-hour or 12-month inspection. Ask for logbook entries showing compliance with the applicable documents.
Wing fatigue life and documentation gaps
A CASA (Australia) airworthiness directive on Baron wing fatigue life retires the wing spar and spar cap structure. For models 58 and 58A it sets a limit of 16,000 hours time in service. The directive's applicability lists 58, 58A, 58TC, 58P and 58PA series and does not name the G58. Ask a Baron-experienced inspector how it applies to a particular G58 and what the airplane's hours are. The handbook supplied covers serials TH-1 thru TH-772, and the weight-and-balance records supplied are for a Model 58 (serial TH-2103), so none of them is G58-specific.
Manual gear extension
The gear uses a large gear box driven by an electric motor and push rods, with a hand-crank on the main drive shaft. There is no hydraulic system, so the gear will not free-fall. Manual extension will not help if a push rod fails, the gear is jammed, only one or two legs extend, or the sector gear breaks. The source article says the newer the airplane, the harder the crank is to turn. It advises practicing the procedure once with a qualified instructor or safety pilot. It also advises leaving the pattern and climbing to at least 1,000 feet above terrain and obstacles before running the checklist.

Safety notes
- Manual gear extension takes time and effort. Do not try it in the traffic pattern or on approach. Get away from the airport and run the checklist.
- If the gear motor breaker has popped, abort the approach and let the breaker cool at least a minute before one reset attempt.
- The POH introduction warns to use only genuine Beechcraft or Beechcraft-approved parts from approved sources. Salvaged or unknown-history parts may hide damage.
- The V/G supplement says to fly by the original POH performance figures, which gives a larger safety margin, even though the kit lowers stall and Vmca speeds.
